2008

(July 5-11, 2008)

Alumroot Heuchera richardsonii (Saxifrage Family Saxifragaceae) a.k.a. prairie alumroot, Richardson's alumroot

Heuchera: after Johann Heinrich von Heucher (1677-1747) professor of medicine and botanist at Wittenberg, Germany

richardsonii: for Sir John Richardson (1787-1865, its discoverer)

Alumroot is a native perennial that grows 1 to 3 feet tall.  The basal leaves are long-stalked and divided into 7 to 9 palmate lobes with 3 to 5 smaller lobes.  The leaves are noticeable in mid-spring, but the flower stalk appears later.  The stalked flowers grow in a loose cluster along a long stalk above the leaves, and there are usually several flower stalks per plant.  The flowers are green to cream in color, and tubular.  The upper surface is about 1/3 inch long and overhangs the shorter lower surface, and the stamens protrude beyond the flower lips.   

Alumroot will grow in dry, moderately wet to wet woodlands and prairies.  The flowers bloom in June and July.  Watch for it along roadsides and in prairie settings throughout the wildlife areas.  A good place to find them is along Abel Road just to the west of where it intersects with Phantom Lake Road. 

In 1798, it was reported that Alumroot's roots have a "very intense astringent" quality.  At that time it was thought to be useful in curing cancers.  In 1828 it was reported to be used by Native Americans as an "external remedy for sores, wounds, ulcers and even cancers".  It may still be used medicinally today in some cultures but a warning was found stating that excessive ingestion may cause gastric irritation and kidney or liver failure.

A garden variety perennial called "Coralbells" was bred over the years from Alumroot, prized for their large ornamental leaves and red, white or green bell-shaped flowers. 

Figwort Scrophularia lanceolata (Snapdragon Family Scrophulariaceae) a.k.a American figwort, early figwort, lance-leaf figwort, hare figwort, carpenter's square

Scrophularia: named in 1474 by an Italian physician who noticed the resemblance between the rhizomal knobs of some species and the tubercular condition of human lymph nodes called scrophula

lanceolata: lance-shaped

Figwort is a native perennial that grows 2 to 6 feet tall.  The stem is square with mostly flat sides.  It may be green or reddish in color.  The leaves grow opposite each other on short stalks.  Each leaf is lance-shaped and toothed, reminiscent of a mint leaf.  The five-parted flowers are green to reddish-brown at the tips and just 1/4 to 3/8 inch long.  They are tubular shaped and have 4 stamens which barely protrude from the petals.  The upper lip of the flower is 2-parted and the lower lip is 3 parted with the center lobe pointing backward.  The flowers cluster loosely in short branches near the top of the plant. 

Figwort prefers open meadows, fields, woodland and wetland edges in rocky soils.  Look for it along Stolte Road at Corduroy Dike and near the rest area along North Refuge Road.

The leaves and roots of Figworts have been used medicinally "Externally, in the form of fomentation, or ointment, it is valuable in bruises, mammary inflammation, ringworm, piles, painful swelling, itch, and cutaneous eruptions of a vesicular character."

Upright bindweed Calystegia spithamaea (Morning-glory Family Convolvulaceae) a.k.a. false low bindweed, low bindweed

Calystegia: from two Greek words kalux, "cup," and stegos, "a covering," and thus meaning "a covering cup" (?)


spithamaea: a span high

 

A native perennial of Wisconsin, Upright bindweed grows low to the ground, with an erect stem that grows 3 to 20 inches high.  The oblong leaves grow alternately up the stem on short leaf-stalks.  The large five-parted flowers are usually white, but sometimes have a pinkish hue and are funnel-shaped.  Each petal is shallowly lobed with large bracts and just below the mostly equal sepals.  The flower usually grows at ground level below the leaf-stalk, although it sometimes grows above it. 

 

Upright bindweed grows in dry forests, woods, fields, and likes rocky and/or sandy soils.  It can be found along most roadsides throughout the wildlife areas, as well as off-road prairie habitats.  There are many plants growing at the James Road/Main Dike Road intersection in the eastern part of Crex where it was burned this spring. 

 

Morning glories are usually twining and climbing vines, found chiefly in tropical and sub-tropical regions.  Convilvere, the Latin root of the family name means "to twine around".  Upright bindweed is one of only two members of this family native to this area.  The other is Hedge bindweed Calystegia sepium, which has similar flowers but triangular leaves on vining stalks up to 10 feet long, and is found in wet disturbed sites, prairies and meadows.  Other morning glories that may be found in Wisconsin (mainly in the southern part of the state) are introduced or escaped from gardens, and one, Field bindweed, Convolvulus arvensis, is considered invasive and should be eradicated. 

(June 28 - July 4, 2008)

Long-headed thimbleweed Anemone cylindrica (Buttercup Family Ranunculaceae) a.k.a. candle anemone, thimbleweed, long-fruited thimbleweed, long-fruited anemone, nimbleweed

Anemone: an ancient Greek name from anemos, "wind"
cylindrica: cylindrical

Long-headed thimbleweed is a native perennial that grows up to 3 feet tall, but usually top out at 2 feet.  The basal leaves and the few leaves up the stem are stalked and deeply divided into 5 main segments, and the segments are toothed or lobed.  The flower grows from a long stalk above the main whorl of leaves, and there are usually several flower stalks per plant.  The flowers have white petal-like sepals, each about 1/2 inch long.  The fruits develop on a dense cylinder up to 1 1/2 inch tall in the center of the flower. 

Another thimbleweed, A. virginiana is also found at Crex, but it has short, oval fruiting heads and only 1-3 leaves in the main whorl, while A. cylindrica has more than 3 leaves in the main whorl.

Thimbleweed prefers dry, well-drained prairies and sandy areas.  It blooms in June and July. 

The name thimbleweed comes from the shape of the fruiting head, which is initially shaped like a thimble.  Some Native American tribes used the leaves for a poultice to treat burns. 

Hedge nettle Stachys palustris (Mint Family Lamiaceae) a.k.a marsh hedge-nettle, woundwort

 Stachys: from the Greek stachus for "ear of grain" or "a spike," in reference to the spike-like form of the flowers.
palustris: "of marshes".

Hedge nettle is a mostly unbranched perennial that grows up to 3 feet tall.  Like most members of the mint family, it has square, hairy stems and opposite leaves.  The stalkless leaves grow up to 5 inches long and 2 inches wide, wider at the base and pointed at the tip.  The flowers occur in several 6-flowered whorls at the top of the stem.  Typically several small leaves occur below each whorl.  The whorls are generally spaced far apart at the lower part of the stem and grow into a denser spike towards the top.  Each flower is about 1/2 inch long with a 5 toothed, hairy, green calyx and a tubular, mottled, pinkish-purple corolla with 2 lips.   The upper lip is hooded and 2-lobed, while the broader lower lip is 3-lobed.  This lower lip is used as a landing pad for pollinating insects, mostly long-tongued bees such as bumblebees, Miner bees, Little carpenter bees, among others. 

Hedge nettle blooms from June into September, and is just beginning to bloom in the wildlife areas.  It prefers wet prairies and exposed shorelines, with light shade to full sun.  It can be found along many of the roadsides near waterways.

It was thought that this herb could be used to heal wounds, which is where the name "woundwort" came from. 

Tall meadow rue Thalictrum dasycarpum (Buttercup Family Ranunculaceae) a.k.a. purple meadow-rue

Thalictrum: from thaliktron, a name used to describe a plant with divided leaves, and a name given to the genus by Dioscorides, the Greek physician and pharmacologist who wrote the Materia Medica, which remained the leading pharmacological text for 16 centuries.
dasycarpum: dasys for "hairy," Latin for "hairy-carpelled" which is the seed bearing organ of a plant.

 This tall plant of woodland edges and wetlands grows 3 to 5 feet tall.  The stems are often purple, which gives it the name "purple meadow rue" in some areas.  The leaves of Tall meadow rue are  alternate and compound, with 3 parts divided three to five times.  The leaflets are 1 to 2 1/2 times as long as they are wide and mostly 3 lobed (Like other rues).  The flowers of Tall meadow rue are individually stalked, green to white in color and are found in clusters near the top of the plant.  Male and female parts grow on separate plants.  Both are 1/3 inch wide and have 4 to 5 white to pale purplish petal-like sepals.  The male flowers have many threadlike stamens, and the female flowers have a small bur-like head of ovaries with a tiny fuzzy stigma.  (The one in the photo has male flowers). 

Tall meadow rue blooms in June and July.  It prefers moist prairies, damp thickets and wet prairies.  Look for them at Crex Meadows and Fish Lake Wildlife Areas along the roadsides near the flowages.  Some spectacular specimens can be found along Lower North Fork Flowage on Hilda's Corner Road. 

Gilmore (1914) wrote of Thalictrum dasycarpum that, among Teton Dakota, "the fruits on approaching maturity in August are broken off and stored away for their pleasant odor; for this purpose they are rubbed and scattered over the clothing.  The Indians say the effect is enhanced by dampness.  This, like all other odors used by Indians, is of slight, evanescent fragrance.  They use no heavy scents; all are delicate and give a suggestion of wholesomeness and of the freedom of the uncontaminated outdoors."

(June 21-27, 2008) Virginia ground-cherry Cypripedium acaule (Nightshade Family Solanaceae) a.k.a lance-leafed ground-cherry, obedient plant

 The Virginia ground-cherry is an erect perennial that grows 12-24 inches tall.  The stems are forked, and the upper parts have stiff hairs.  This ground cherry has elongated lance-shaped leaves.  As with the other ground-cherries of the area, the five-petaled flower is dull yellow on the edges and outsides of the petals, with a reddish-brown center.  It is funnel-shaped, When observed from above, the flowers nod towards the ground.  Only when the flower is lifted can the inside be observed (which makes it sort of difficult to photograph without making some non-natural adjustments).  The fruit is a small, yellow, and reminiscent of a tomato, and is wrapped in a paper-like husk consisting of five

The other ground-cherry on our plant list is the Clammy ground-cherry.  It blooms a few weeks later than the Virginia ground-cherry.  It has wider, rounder leaves, but the flower is nearly identical.

The Virginia ground-cherry is a cousin of the tomatillo (Physalis philadelphica), which is used in Mexican cooking (salsa verde).  I could not find any source specifically listing the Virginia ground-cherry's fruit, which looks much like it's cousin, as edible, however, the fruits of many of the other ground-cherries that grow in the US and other countries are listed as being edible, mainly cooked and put into sauces and pies, as well as being eaten raw, so it can be assumed that perhaps the fruit of the Virginia ground-cherry can be eaten too.  I will let you know (if I live that long!).

 Tufted loosestrife Lysimachia thyrsiflora (Primrose Family Primulaceae) a.k.a. swamp loosestrife

 The yellow flowers of this 1 to 2 1/2 foot perrenial are six-parted, and 1/3 inch wide.  The petals are linear, with black marks, and the separate stamens are twice as long as the petals.  The flowers grow in dense round clusters spreading from the middle leaf axils.  The leaves are dotted and narrowly lance-like.

Tufted loosestrife grows in wet bogs, marshes and shallow waters.  We found it growing i Crex Meadows along Main Dike Road across the road from Dikes 4 and 5 at the edges of the sedge marshes.

This is a native plant, not invasive like the introduced Purple loosestrife.  There are 5 native loosestrifes found at Crex and the other GLG-managed properties, all yellow, including Swamp candles, Fringed, Lowland, Whorled and Tufted loosestrife. 

BACK TO TOP

(June 14-20, 2008) Moccasin flower Cypripedium acaule (Orchid Family Orchidacea) a.k.a pink lady's slipper

 The Moccasin flower is an erect perrenial that rows 8 to 16 inches tall.  There are only basal leaves, two of them, that are oblong and have pointed tips.  Each leaf is heavily ribbed and clasp the hairy stem.  The solitary pink flower is a six-parted pouch that is 1 1/2 to 2 1/3 inches long. It has red or dark-pink veins and is hairy inside.  The sepalas and petals are brownish with green stripes.

Moccasin flowers grow in dry to wet woods, swamps and pine plantations in acidic, sandy soil.  Most of the flowers identified at the GLG properties were found in red pine plantations.  The one pictured above is growing in the pines between the visitor center parking lot and the camp at Crex Headquarters.   

Native Americans used the flower for decorating their hair.  In the northeast it was used as a nerve sedative.  The USDA reports that "it appears to be a gentle nervous stimulant or antispasmodic, and has been used for the same purpose as valerian."

 False Heather Hudsonia tomentosa (Rock-rose Family Cistaceae) a.k.a. Wooly beach-heather

The bright yellow flowers of this low-growing evergreen shrub are five parted, and 1/4 to 1/3 inch wide.  Several flowers grow from each stem.  The leaves are scale-like and barely noticeable, with dense whitish hairs. 

This plant is perhaps easily overlooked since when out of bloom it appears as a dead shrub, which may explain why no one has added it to  the GLG plant list before now.  It has not previously been indentified on the GLG properties but is known to be present in Burnett County. 

We found these plants on the south end of Stolte Road in Fish Lake Wildlife Area.  It probably appears in more areas, as it's preferred habitat is the sandy soils of dry beaches and inland sands. 

BACK TO TOP

(June 7-13 2008) Indian paintbrush Castilleja coccinea (Snapdragon Family Scrophulraiaceae) a.k.a Painted cup, Prairie fire

 

The true flowers of the Indian paintbrush are actually yellowish in color, two-lipped and tubular.  The leafy, three-lobed scarlet bracts surround the flower and are the most prominent part of the plant.  The stem leaves have 3 to 5 deep lobes and the basal leaves grow in a rosette.  The stem is hairy and erect.  The plant may grow 8 to 20 inches high, and the "flower" may appear at any height.

Indian paintbrush can be a common flower at Crex and Fish Lake during wet seasons.  It was noticeably absent in 2007 when the prairies and wetlands suffered from drought.  It inhabits moist meadows and blooms here from late may into early July if it's habitat remains moist. 

Look for this strikingly beautiful plant at Fish Lake Wildlife Area on County O west of Stolte Road and at Crex Meadows in the far eastern side along Klotts Road.  It may appear at other sites, but these have been historically the most consistant.

Yellow star-grass Hypoxis hirsuta (Lily Family Liliaceae) a.k.a. Stargrass, Yellow stargrass, Common Goldstar, Common Stargrass

This diminutive yellow flower is similar to blue-eyed grass in habitat and appearance, with a great difference in color.  It's leaves are grass-like, with spreading hairs, and grow 4 to 12 inches long. The yellow flower appears when the plant is 3 to 6 inches high. The flowers are 1/2 to 3/4 inches wide and have 6 petals.  There are 2 to 6 flowers per plant in an irregular  long-staked cluster.    

We found this plant on Hickerson Road in Fish Lake Wildlife Area.  It has also been identified at Crex Meadows near Monson Lake.  It prefers dry meadows and open woods.

BACK TO TOP

(May 31 - June 6 2008) Wild columbine  Aquilegria canadensis (Buttercup Family Ranunculaceae)

 As you drive through the wildlife areas over the next several weeks you may notice a shortish plant with red flowers loosely scattered across the plant.  Upon closer examination, you will find one of the most striking flowers that grow in this area.

Wild columbine is a 1-2 foot tall plant with reddish stems and blueish-green leaves.  The branches are slightly hairy and branched.  The leaflets grow in threes and each leaf is lobed into three divisions.  The flowers dangle from arching stalks along the upper half of the plant.  Each flower is about 1 1/2 inches long with 5 petal-like sepals and 5 yellow tipped petals with backward-protruding hollow spurs.  Yellow stamens protrude from the flower.

Columbine grows in many areas of all the wildlife refuges, from dry upland prairie habitat to moist woodlands and all habitats in between.   They are widespread and common. 

The nectar of Wild columbine is a favorite of hummingbirds and long-tongued moths such as the hummingbird moth.  The hollow spurs, when broken and sucked on, produce a nectar that tastes like honey.  Native Americans used the seed of Wild columbine to relieve headaches. 

BACK TO TOP

(May 24-30, 2008) Wood betony  Pedicularis canadensis (Snapdragon Family Scrophulariaceae) a.k.a. Lousewort

 Wood betony is a partially parasitic plant that grows in large clumps.  The leaves are deeply lobed and appear fern-like.  Basal leaves grow up to 6 inches long.  The flowers grow on the top of the hairy stems in a dense cluster.  Each flower is directly above a small leaf-like bract, and is about 1 inch long with a hairy green calyx with a slanting mouth and a pale yellow, tubular 2-lipped corolla. 

Wood betony is found in dry to mesic prairies, open woodlands and meadows.  Look for it in Crex Meadows near Abel road and Fish Lake Wildlife Area along the south end of Hickerson Road growing among hoary puccoon.

BACK TO TOP

(May 17-23, 2008) Bird's-foot violet Viola pedata and Prairie violet Viola pedatifida (Violet Family Violaceae)

The bird's-foot violet is one of eleven different violet species found within the GLG-managed properties.  There are eight blue violets, and this is probably the most striking of them all.  The bird's-foot violet's leaves are divided into three narrow segments radiating from a single point.  Each main leaf segment is usually further lobed and divided.  All of the leaves are on individual stalks coming from the roots.   The flower is mainly a pale-blue to rich violet in color, and the ones commonly found here have a half-white lower petal.  The petals are hairless on the inside.

 The 5 large orange stamens of the Bird's foot violet are prominent in the center of this flower, which differs from the similar prairie violet (viola pedatifida) which is densely bearded with hairs on the lower half of their inside surfaces with no protruding stamens.  The Prairie violet's leaves are also divided into three segments with further segmentation of each leaf segment.  The flower is violet purple in color.  

The Bird's-foot violet is usually found on sandy, rock soils in prairies and savannahs, but can also be present on mesic, black-soiled prairies.  The Prairie violet is found more often on higher-quality soils, although it can be found on sand too, as the one in this photo was (just a few feet from some Bird's-foot violets).  Both violets bloom in May and June.  Some areas of the country can see a fall bloom for these as well.

Look for these and other violets throughout the wildlife areas in open prairie settings and along roadsides.  A good spot is along North Refuge Road near Rices Lake in Crex or Jimmy Carter Road and Stolte Road in Fish Lake Wildlife Area.

(April 26- May 16, 2008) Prairie Buttercup Ranunculus rhomboideus Goldie (Buttercup Family Ranunculaceae)

The prairie buttercup is a native prairie plant that grows in full to partial sun in dry prairies and woodlands.  It is a small perennial that grows only 2 to 8 inches tall.  It is hairy throughout, with long, soft hairs on the leaves and stems.  The basal leaves are up to 2 inches long and about as wide, with coarse, rounded teeth or even, small lobes.  There are usually several individually staked flowers per plant.  Each flower is about 3/4 inch side with 5 small, hairy sepals and 5 yellow petals surrounding many yellow stamens.

Look for this lovely little flower throughout the wildlife areas in open prairie settings.  The one photographed above was found near the intersection of James Road and Main Dike Road at the east end of Crex Meadows Wildlife Area just last week.  It blooms from mid-April into May.

BACK TO TOP

(April 12-25, 2008) Pasqueflower Anemone patens (Buttercup Family Ranunculaceae)

We are continuing the Pasqueflower as the species of the week for a second week, it has started blooming April 19 and can be found near Reigel Overlook. 

The Pasqueflower is a lovely, short stocky perennial wildflower of rocky ridges in prairie habitat.  It is one of the earliest bloomers, usually showing it's lovely blue to purple to pink to white petals in early to late April into early May.  The stems and leaves of the plant are hairy throughout.  The leaf is palmately-divided into fine segments, kidney-shaped in outline, basal leaves long-stalked, a whorl of stalkless leaves beneath the flower.  The plant grows 4 to 16 inches tall.  The flower has 5-7 parted petals 1 to 1 1/2 inches long. 

Look for this lovely flower on the ridge west of Reigel Overlook. It may occur in other similar habitats throughout Crex Meadows, and there are a few plants that have taken root in the wildflower garden in front of the Crex Meadows Wildlife Education and Visitor Center.  In 2007 the flowers were in full bloom by April 15.  This season it may be a bit later due to the cold weather and late winter, but we expect to see the flower blooming (hopefully) when this last round of snow melts.

2007

(September 8-14)  Smooth Aster Aster laevis Aster family Asteraceae

Like all asters, the blue asters are difficult to positively identify, so I will focus on the most common blue aster found in this area.  Most of the true asters hybridize with each other, which makes everything even more confusing.  But regardless of their true identity, the blue asters, when in fresh bloom, display breathtaking hues of blue and purple. 

The Smooth Aster is a perennial growing 1 to 3 feet tall with hairless stems that may take on a reddish hue towards the bottom.  The leaves grow along the stem and can be quite variable in size and shape. They are alternate, lanceolate to broadly ovate to almost linear, may be smooth or toothed, are thick and firm, and clasp the stem. They can be up to 4 inches long and .8 inch wide, but are usually smaller.  There are usually no leaves at the top of the stems where the flower branches begin.  The 15 to 25 ray petals are bluish to pale-purple and 1/4 inch to 3/4 inch long. The flowers grow on short thin stems and each plant may have a few or many flowers, varying in size from 2/3" to 1 1/4 inch in diameter.  The center disks are yellow or orange-brown (possibly from hybridization).

Smooth Asters prefer full to partial sun and dry to moderately moist sandy or loamy soil.  They grow in prairies, woodland openings, and along roadsides.  They bloom from August into October.  The prairie planting walk at the Crex Meadows Visitor Center has a nice display in bloom.  Look for these and other blue and white asters throughout the Crex Meadows and Fish Lake Wildlife Areas.  The prairie planting walk at the Crex Meadows Visitor Center has a nice display in bloom.

(September 1-7) Spotted jewelweed Impatiens capensis (Touch -me-not Family Balsaminaceae) a.k.a orange jewelweed, orange touch-me-not, spotted touch-me-not

Spotted Jewelweed is a annual plant growing 2 to 6 feet tall with a smooth stem that branches near the top.  The stems are hollow and succulent.  The leaves are soft, lightly toothed  and slightly like an elongated heart.  The orange spotted flowers are cornucopia-shaped, with 5 petals 3/4" to 1 1/4' long, and grow at the end of thin stalks in a drooping manner.  The seed capsules are about an inch long and become plump when ripe and then explode when anything touches them.  This plant is closely related to the tropical impatiens that are used as bedding in shady landscapes.

Spotted Jewelweed prefers wet, shady places and can be found from July through mid-September along many of the wetland edges at Crex, especially in Fish Lake Wildlife Area.  Check out County Road O for a nice close-up look.  They grow thickly along the ditches there.

BACK TO TOP

(August 25-31) Sand evening primrose Oenothera clelandii (Evening Primrose Family Onagraceae) a.k.a. Cleland's Evening Primrose (named for Ralph Erskine Cleland, 1892-1971, American botanist who studied Oenothera)

At first glance, the Sand Evening Primrose is very similar to the Common Evening Primrose, which is widespread at Crex Meadows and Fish Lake Wildlife Areas.  But a closer look (you have to get out of the car and look at it up close!) will tell you that this species has many differences, most conspicuously the shape of the flower.  The Common Evening Primrose flower has heart-shaped petals, while the Sand Evening Primrose has diamond-shaped to oval-shaped petals.  Also, while the Common Evening Primrose can grow up to 9 feet tall (but the plant is seen in many shapes and sizes, from short and stubby with many branches to tall with one or few branches) the Sand Evening Primrose rarely grows over 3 feet tall.

Specimens found at Fish Lake Wildlife Area this summer were only a foot or two tall and had many branches growing out in a radius from the same rootstalk.  The flowers are a 1/2 inch to 1 1/2 inch wide, and flower from a 3-12 inch spike at the top of the stalk.  The fruit is a curved, tuft-less capsule, and the long, lance-like leaf grows alternately on the stem. 

Sand Evening Primrose is a native species to Wisconsin, more common in the southern part of the state.  Only a few specimens have been observed at Fish Lake Wildlife Area, and there is record of it being observed near the sand blow at Crex Meadows Wildlife Area.  It blooms in August and September. 

BACK TO TOP

(August 18-24) Rough blazing star Liatris aspera (Aster Family Asteraceae) a.k.a. lacerate blazing-star, tall gay-feather

The most common of the blazing stars in this area, the Rough Blazing Star is widley variant in it's appearance.  Most commonly, it grows in a long spike, up to 4 feet tall with either hairy or smooth stems and numerous alternate, smooth-edged leaves.  The lower leaves are longest, up to 16 inches, and are as wide as 2 inches at the center. The leaves grow shorter towards the top of the plant and usually end below the flower spike, but, as in the photo to the left, can grow among the flower heads as well.  This usually occurs when the plant has been disturbed (eaten, cut) before the flowers appear.  Some disturbed plants grow up in thick clusters low to the ground.  The flower heads grow alternately at the top of each stem, and are about an inch wide or smaller.  There are 16 to 35 small purple disk flowers, each with a small corolla of 5 lobes and 2 conspicuous thin styles.

Rough Blazing Star is common in prairie regions and can be found throughout Crex Meadows and Fish Lake Wildlife Areas along the roadsides and in the dry meadows.  They grow better in areas with few plants and becomes more abundant following a fire.  This year the plant is extremely abundant, especially where controlled burns occurred this spring.  Occasional white plants, lacking the purple pigment in both the flower and the stem, have been found here, more often in Fish Lake Wildlife Area.  The plant blooms beginning in mid-July through August.

The genus Liatris means "lost in antiquity" and the species aspera means "rough" or "harsh" from the coarse nature of the leaves.  

BACK TO TOP

(August 4-10) Field Milkwort Polygala sanguinea (Milkwort Family Polygalaceae) a.k.a Blood Milkwort, Purple Milkwort

Field Milkwort is a diminutive annual that rarely grows more than a foot tall.  It has slender, un-branched or few-branched stems with thin alternate leaves.  The flowers grow in short, dense cylindrical heads at the top of the plant.  Each individual flower is rose purple to white, and less than 1/4 inch long.  they have 5 sepals, with the upper one and lower two a green color.  The 2 side sepals are deep pink to white like the three small petals, which form a small tube. 

The Field Milkwort blooms from July to September.  They prefer moist woods, fields and prairies.  Fish lake Wildlife Area is a good place to find them, along the Southwest Dike road.  There are four other milkworts that have been found at Crex, the Cross-leafed Milkwort Polygala cruciata, which has white flowers and is a species of special concern in Wisconsin, and the Racemed Milkwort Polygala polygama, with larger, looser flower clusters, Seneca Snakeroot Polygala senega, a taller plant with a longer-stalked cluster with rounded greenish white flowers that blooms in late spring and early summer, and Whorled Milkwort Polygala verticillata, a species similar to the snakeroot but with whorled leaves.  Field Milkwort is more common in this area than all of the others.

The Milkwort's genus Polygalaceae is derived from the Greek word polys, "many or much," and gala, "milk," since it was thought that the presence of some of the species in a pasture increased the yield of cow's milk.  The species name sanguinea is Latin for blood red.

(July 28 - August 3) Giant Sunflower Helianthus giganteus (Aster Family Asteraceae) a.k.a. Swamp Sunflower, Tall Sunflower

The Giant Sunflower is a tall sunflower growing up to 6 feet tall with reddish-purple stems.  The leaves are opposite on the lower stem, alternate on the upper branches, flat, narrow, and at least 3 times as long as they are wide.  The yellow heads grow one per branch, and are 1 1/2 to 2 1/2 inches wide.  They have 10-20 pointed yellow rays surrounding a yellow disk of small 5-lobed tubular flowers.

The Giant Sunflower blooms from mid-summer into fall.  They are occasional, preferring open sites near water.  Fish lake Wildlife Area is a good place to find them, along Stolte and Hickerson Roads along the dikes.  Many other sunflower species can also be found at Crex Meadows, Fish Lake and Amsterdam Sloughs, including Maximilian's, Western, Stiff, Prairie and Rough-leaved sunflowers.

The Sunflower's genus Helianthus is derived from two Greek words helios, "sun," and anthos, "flower," in reference to the sunflower's supposed tendency to always turn toward the sun.

Spotted Joe-Pye-weed Eupatorium maculatum (Aster Family Asteraceae) a.k.a. Thouroughwort

These plants grow up to 7 feet tall with unbranched stems that are spotted purple or purple throughout.  The leaves are widely spaced in whorls of 4 to 6 leaves.  The leaves are coarsely toothed and is widest at the middle and can grow up to 9 inches long and 3 inches wide.  The flower heads are in a flat or slightly rounded cluster at or near the top of the plant.  The flower head is narrow, less than 1/2 inch wide.  It has one to two dozen flowers which are pink to purplish with thin purple styles extending from each flower when in full bloom.

Spotted Joe-Pye-weed is a perennial plant native to this area.  It blooms from late spring to early fall, but seems to be in full bloom in this area from mid July to early August.  It is very common along the edges of waterways and wetlands.  It can be found throughout all of our Wildlife Areas where there is water.

The swamp milkweed is common in the same habitat as Spotted Joe-Pye-weed, but it blooms earlier in the summer and has long, slender leaves and green stems that can sometimes be purplish only just below the flower head.

The genus Eupatorium is derived from the Greek name Mithridates Eupator, King of Pontus about 115BC who is said to have discovered an antidote to a commonly used poison in one of the species.

(July 21-27) Prairie Blazing Star Liatris pycnostachya (Aster Family Asteraceae)

These slender, spike-like plants can grow up to 5 feet tall.  They have grass-like leaves and hairy stems.  The lower leaves are longest, up to 1 foot long and 1/2 inch wide, and the leaves grow progressively shorter and thinner towards the top of the stem.  The flower heads grow in a dense spike at the top of each stem, the spike can be anywhere from a few inches to a foot and a half long.  Each flower head has 5 to 10 5-lobed purple flowers, with 2 prominent purple styles coming from each flower.  A similar species, Marsh Blazing Star Liatris spicata also blooms in this area during the same time, but it has smooth, hairless stems and the bracts at the base of each flower head are flat against the head and bluntly rounded, while the bracts of the Prairie Blazing Star are pointed and curve outward. 

Priaire Blazing Star blooms from mid-summer into fall.  They are a common plant in tallgrass prairies.  These are just beginning to bloom here and can be found throughout the wildlife areas, but a sure spot for them is the prairie at the intersections of Phantom Lake Road, Abel Road and Main Dike Road in Crex Meadows.

Blue Vervain Verbena hastata (Vervain Family Verbenaceae)

These plants grow up to 6 feet tall and have erect branches and opposite leaves.  The pointed, toothed leaves  can grow as long as 7 inches and about 2 inches wide.  The larger leaves may have 2 toothed lobes at the base.  There are many erect flowering spikes growing in a cluster at the top of each plant.  The flowers are purplish or blue and are less than 1/4 inch wide.  They have a small 5-toothed green calyx and a 5-lobed blue to purple corolla.  The flowers bloom a few at a time from the bottom of the spike upwards.

Blue Vervain is very common along the edges of waterways and wetlands.  It can be found throughout all of our Wildlife Areas where there is water.  Look for it especially along Phantom Lake Road and main Dike Road in Crex. 

The plant has been used for medicinal purposes for centuries.  It was used as a expectorant and it was said to "heal a green wound within 24 hours"7

Another Vervain growing in this area, the Hoary Vervain Verbena stricta, which has larger, thicker spikes with pinker flowers, is noted as being bitter-tasting and is avoided by livestock and can become abundant in overgrazed uplands1.

(July 14-20) Silky prairie clover Dalea villosa (Bean Family Fabaceae)  a.k.a. Downy Prairie Clover

This beautiful flower is closely related to Lead Plant in it's leaf structure, although the leaves are a much lighter, mossier green overall.  It has 11-17 narrow, elliptical leaflets divided into an odd number.  The plant stands 12-24 inches tall and has light purple to pink flowering spikes at the end of a long stem.  The flowers are five-parted and bloom from the bottom of the spike to the top over several days. 

Although much more common in prairie states to our west such as the Dakotas, Silky Prairie Clover is a species of Special Concern in the state of Wisconsin, occurring in only a handful of counties along the west central border.  It prefers dry, sandy soils in prairie habitats. 

There are a few plants to be found in this area, although their location is hard to pinpoint.  If you are lucky enough to find one, please take precaution not to disturb the plant so it can have a chance to propagate and become more common in our area.  It is never OK to dig up or even pick wildflowers and other plant species in State-owned wildlife areas.  View them, photograph them, and then leave them behind so that others can enjoy them too.

(July 7-13) Wild bergamot Monarda fistulosa (Mint family Lamiaceae) a.k.a. Beebalm, Horsemint, Lemon-mint, Purple bergamot

Wild Bergamot is a fragrant mint that grows up to 5 feet tall.  It's stems are square with a few to many branches, and the upper stems are usually hairy.  The toothed leaves grow opposite each other and can grow up to 5 inches long and 2 inches wide.  They are broad at the base and taper into a point.  The lavender flowers are in round clusters at the top of the stems.  The complex flower components grow from the rounded head; the 1/2 inch long calyx is a narrow tube with 5 spiny points and many white hairs at the mouth.  The corolla has 2 long lips at the end, the upper one hairy and the lower one three-lobed.  Two stamens and the style protrude below the upper lip.

Wild Bergamot grows throughout Crex Meadows and the surrounding area.  It can be found along most roadsides and in the prairies.  It blooms from mid-June through early fall in this area.  

The Ojibwa used the root as a stomach pain-relieving tea.  The scent of the plant is reminiscent of of the oil of the Mediterranean Bergamot tree which is used a a flavoring for Earl Gray tea.  Thoreau wrote of the plant, "At roadside opposite Leighton's, just this side of his barn, Monarda fistulosa, wild bergamot, nearly done, with terminal whorls and fragrance mixed of balm and summer savory."

Pickerelweed Pontederia cordata (Water-hyacinth Family Pontederiaceae)

Pickerelweed is a water plant that grows up to 3 feet tall and has long, thick-stalked triangular leaves that grow up to 8 inches long and 3 1/2 inches wide.  They are heart-shaped and taper into a blunt tip.  There is one smaller but similarly shaped leaf and a clasping sheath just below the flower.  The flowers grow in clusters at the top of each plant and are 1/2 inch long.  They have 3 narrow lower lobes and 3 upper lobes with 2 bright yellow spots on the center lobe.  3 thin, curving stamens grow from the center of the flower.

Pickerelweed is common throughout the waterways of Crex and Fish Lake, growing in the shallow muddy shorelines.  A good place to see them is along the dike road at Phantom Lake, especially the southern end.  It blooms from mid-summer into early fall. 

Native Americans called Pickerelweed Wampi and they used the seeds as a food source eaten directly or ground into a flour.  In Britian it was widely thought that young pike (called Pickerel) were products of Pickerelweed, that the parents both ate the weed and bred on them, which is most likely where the common name came from.

(June 30-July 6) Lead plant Amorpha canescens (Bean family Fabaceae) aka. Prairie Shoestring, Shoestrings, False Indigo, Leadwort, Wild Tea

 Lead Plant's beauty is in it's complexity.  It's leaves are stalked and divided into as many as 51 narrow leaflets, each up to 3/4" long and 1/2" wide.  The plant can be single-stemmed or contain a few branches, and can grow up to 3 feet tall.  The small gray to violet purple flowers grow in dense clusters at the top of the stems. Each flower has a tiny, hairy, green group of 5 sepals and a single 1/4" long purple petal curling around the 10 protruding orange-tipped stamens1.

Lead Plant is abundant in this area and can be readily found throughout all of the properties managed by the Crex crew.  It grows in  well-drained prairies, savannahs and roadsides.  It begins blooming in late -June and will continue through mid-July.  A great place to find large groupings of Lead Plant is the west end of North Refuge Road.  Some of the plants there are growing as large shrubs, 3 feet tall. 

Parts of this plant have been used as medicine and a yellow tea can be made from the leaves1.  The scientific name Amorpha comes from the Greek amorphos, meaning "deformed" because of the absence of four of the petals on the flower7.  It was once thought that the plant indicated the presence of lead7, but it is most likely named for the usual color of the flowers, appearing a lead-colored gray at first glance.

Prairie larkspur Delphinium carolinianum (Buttercup family Ranunculaceae)

Prairie larkspur plants grow up to 3 1/2 feet tall. Each finely-divided leaf grows alternately up the stem denser near the bottom and sparse towards the top.  The flowering spike at the top of each plant is about ten inches long and contains up to 30 large, whitish-blue flowers. The irregular flowers are shaped like a cornucopia, open with 5 petals at the front and curving back into a long, tubular spur, and 4 smaller white to bluish petals, the lower two of which are each split into 2 hairy lobes1.

Prairie Larkspur prefers dry upland prairies and pastures.  It is more frequently found in the western tallgrass region, but is found sporadically eastward.  The best place to find Prairie larkspur in Crex Meadows is along the west end of North Refuge Road, where there is a large field filled with the plant on the south side of the road.

The juices or seeds of many of the Delphiniums were used by various native peoples worldwide as insecticides, internal parasiticides, and to control lice and ticks; the flowers were made into green or orange dyes. Seeds of prairie larkspur were used by the Kiowa tribe in their ceremonial rattles.

The generic name Delphinium derived its name from the Latin for "dolphin," which the shape of the flowers somewhat resembles. The plant was first described for science by Thomas Nuttall in his book Genera of North American Plants of 1818.

(June 23-29) Butterfly Milkweed Asclepias tuberosa (Milkweed family Asclepiadaceae) aka. Butterfly Weed, Pleurisy Root

 The Butterfly Milkweed is one of 6 species of milkweed found in the Crex Meadows area.  It is a stout plant that can grow up to 3 feet high.  The hairy, dagger-shaped leaves are narrow  and stalkless and about 4 inches long and an inch or less wide.  The ride alternately but occasionally opposite on the stem.  It's bright orange flowers cluster at the top of the stem where the leaves join.  There can be up to 25 individually stalked flowers arranged flatly on each stem with 5 reflexed petals below 5 erect hoods.  The hairy seed pods from this milkweed are 6 inches long and less than an inch thick.

The Butterfly Milkweed is abundant in this area and can be readily found throughout all of the properties managed by the Crex crew.  It grows in  well-drained prairies, savannahs and roadsides.  It begins blooming in mid-June and will continue through mid-July.

Native Americans used the roots as food, and both Native Americans and European settlers used the roots as medicine1.

(June 16-22) Oval-leafed Milkweed Asclepias ovalifolia (Milkweed family Asclepiadaceae) aka. Dwarf Milkweed

The Oval-leafed Milkweed is one of 6 species of milkweed found in the Crex Meadows area.  It is also one of the shortest, growing only up to a foot tall.  It's white 5-petaled flowers grow in clusters at the top of the plant and attract many insects, including butterflies and bees.  Milkweeds "trap" visiting insects in grooved polliniums on the flowers, and the insect can only free itself be removing the pollen from the groove.  The insect will then travel to another milkweed and insert the pollen into another groove. 

The Oval-leafed Milkweed is considered Threatened in Wisconsin.  It is locally common and can be readily found in this area, especially in the Fish Lake Wildlife Area.  It grows in undisturbed (un-tilled) dry prairies, savannahs and roadsides.  It is the earliest bloomer of all the local milkweeds, beginning in early June.  When the rest of the milkweeds begin blooming in mid- to late-June and early July, the Oval-leafed Milkweed's flowers are past it's prime. 

During World War II Milkweed was a highly sought-after plant when it was discovered that the silky floss from the pods is 5 to 6 times more buoyant than cork and that lifejackets containing just a few pounds of the floss could hold up a 150 pound man in the sea.  It is also warmer than wool and 6 times lighter7.

(June 9-15) Common spiderwort Tradescantia occidentalis (Spiderwort Family Commelinaceae) aka. Widow's Tears.

The Spiderwort is an interesting plant with long parallel-veined, grass-like leaves that fold lengthwise forming a V shape.  The entire plant cam grow to 3 feet tall.  The flowers cluster with up to 10 flower per stem.  The 1-2 inch wide violet-blue flowers have 3 petals with 6 yellow-tipped stamen in the center.  The flowers open only a few at a time in the morning and usually wilt by late afternoon, lasting only one day before decaying into a sticky, wet residue resembling teardrops.  The Spiderwort received it's name because the sap from the leaves, when broken, resemble spider webs. 

The Spiderwort grows in savannahs and prairies and along roadsides.  They can be found  throughout Crex Meadows and other GLG-managed Wildlife Areas.  A good place to look for them right now is along the Hay Creek trail east of the Crex Meadows Wildlife Education and Visitor Center.  There are also a few plants in the prairie plant display at the front of the Visitor Center.

Spiderworts are native to this area and are a perennial. 

When this plant is exposed to air pollution, it's flowers change color, from the violet blue to purplish pink and has been used as a natural barometer for air quality2.

(June 2-8) Large-flowered beardstongue Penstemon grandiflorous (Snapdragon  Family Scrophulariaceae)

The Large-flowered beardstongue is a striking plant that grows 3-4 feet  in height with thick, waxy, rounded leaves that are a bluish green color.  The 2" long, purple, tubular flowers grow on individual stalks in groups of 2-6 at the tops of the stems1

The Large-flowered beardstongue grows in upland prairies, most often in sandy sites.  They can be found widely scattered throughout Crex Meadows and other GLG-managed Wildlife Areas, but the best place to see them is at the Visitor Center in the prairie wildflower exhibit near the entrance to the building.  They bloom in June, and are in bloom this week.

The Large-flowered beardstongue is a native, short-lived perennial.  Some years there are dozens of plants in a given area, while in other years they seem to disappear.  It seems that they may need some soil disturbance to encourage new growth.  Depending on how they are propagated, they may take two years to bloom2.

Native Americans used this plant as a toothache remedy.

(May 26-June 1)) Hoary puccoon Lithospermum canescens (Borage Family Boraginaceae) a.k.a. yellow puccoon 

Hoary Puccoon is a perennial prairie wildflower found throughout Crex Meadows along roadsides and in dry meadows.  Native Americans used the root to make a red dye and the plant was used as a leaf tea to relieve fevers and seizures.  It's bright yellow flowers bloom from early May into June.  The genus name of the plant means "stone-seeded" and the plant is appropriately named. The nutlets are very hard when mature and resemble small polished stones.    

(May 19-25) Lupine lupinus perrenius (Bean Family Fabaceae) a.k.a. Indian beet, Old maid's bonnets, and Sundial lupine

Lupine is a perennial prairie wildflower in the Fabaceae family and can be found all over Crex Meadows, Fish Lake and Amsterdam Soughs Wildlife Areas.  It begins blooming in May and can be found through June and into July.  It's flowers are blue-violet but fade to white as the plant ages.  They have an easily recognized leaf shape, with soft green or silvery leaves divided into 5–17 finger-like leaflets that diverge from a central point. The flowers are produced in dense whorls on an erect spike, each flower 1-2 cm long, with a typical pea flower shape. The fruit is a pod containing several seeds.
