When I first photographed today’s featured wildflowers two summers ago, I hoped I had found a new (to me) native species. A friend thought the flowers might be Canada frostweed. Alas, John Pearson of the Iowa Department of Natural Resources confirmed the ID as a weed with origins in Eurasia.

Moth mullein (Verbascum blattaria) has become widespread throughout the U.S. and Canada. According to the Illinois Wildflowers website, the plant thrives in sub-optimal habitats, such as “pastures, abandoned fields, vacant lots, irregularly mowed lawns, areas along roadsides and railroads, and gravel bars along rivers. It prefers highly disturbed areas and is not invasive of natural areas to any significant degree.” Indeed, I’ve never seen moth mullein on a native or restored prairie. I took all of the enclosed pictures along the Meredith Trail between Water Works Park and Gray’s Lake in Des Moines, disturbed ground that was once a rail line.

Though my editorial bias favors native plants, Iowa wildflower Wednesday has occasionally showcased non-natives, even some considered undesirable weeds. After last week’s red, white, and blue extravaganza, I felt like posting pictures of pretty yellow blossoms today. (White is supposedly a common color variation for moth mullein flowers, but I’ve only ever seen the yellow variety.)

Happy July 4 to the Bleeding Heartland community! In recent years, I’ve marked this holiday by posting Windsor Heights parade pictures or the names of state lawmakers who voted to legalize fireworks sales in Iowa.

Since Independence Day falls on a Wednesday this year, I decided to showcase Iowa wildflowers that display the colors on the American flag. The blossoms in the top image are trumpet vine, Canada anemone, and common blue violets. Follow me after the jump for 34 more species…

Mid-summer is a fantastic time for wildflower-spotting in Iowa. If you visit a prairie habitat this weekend or on July 4, you may see common milkweed, yellow coneflowers, pale purple coneflowers, and purple prairie clover nearing their peak. Wild petunia and black-eyed Susans have started blooming. Along wooded trails, you may find American germander. The non-native (but much-loved by pollinators) chicory flowers are abundant along roadsides. Be careful not to brush up against any wild parsnip–the sap can cause a blistering rash after sun exposure.

Purple poppy mallow (Callirhoe involucrata) is often called a “showy” flower. Its magenta or maroon petals have given the species the common name winecup, and you are unlikely to overlook them if you are anywhere in the vicinity. The first blossoms typically appear in May in central Iowa, but this plant has a relatively long blooming period. I found quite a few flowers on June 27.

According to the U.S. Department of Agriculture, purple poppy mallow is is native to most of the Midwest and the plains. The Illinois Wildflowers site notes, “this plant often grows in poor soil that contains sand, gravel, or clay.” It can thrive in “dry prairies, areas along railroads and roadsides, and abandoned fields.”

The Missouri Botanical Garden’s website says purple poppy mallow can provide “Good native ground cover” for “Border fronts, rock gardens, native plant gardens, wild gardens, naturalized areas or meadows. Sprawl over a stone wall. Fits well into both formal garden areas as well as wild/naturalized areas.” The plant is drought-tolerant.

I’ve wanted to write about these flowers for years but held off because I find them difficult to photograph. The petals often end up looking flat, like shapes in a Matisse painting. I took all of the enclosed pictures this month at prairie plantings along the Meredith bike trail in Des Moines, near SW 9th St and MacRae Park.

Although I was in a hurry to get to the farmers market two Saturdays ago, I had to pull off the bike trail to get a closer look at the bright yellow flowers near the bank of Walnut Creek. They turned out to be Lanceleaf coreopsis (Coreopsis lanceolata), a new find for me. Sometimes known as sand coreopsis or lanceleaf tickseed, this species is native to most of the U.S. and Canada. UPDATE: Bleeding Heartland user Prairie Fan notes in the comments that The Vascular Plants of Iowa, a classic text by Lawrence Eilers and Dean Roosa, identifies lanceleaf coreopsis as a native of the U.S. but not Iowa.

Like other members of the aster family, what looks like one flower is a group of ray flowers (which resemble petals) surrounding a center disc containing many tiny flowers. The ragged tips of the ray flowers set lanceleaf coreopsis apart from most other related species, except for large-flowered coreopsis. I’m grateful to ecological consultant and photographer Leland Searles, who looked at my pictures and confirmed the ID as lanceolata plants, based on the leaves.

Wendie Schneider took the picture at the top of this post in Story County, along with a few other photographs below. The rest of the images are my shots of the colony near the Walnut Creek trail, close to the border between Des Moines and Windsor Heights.

This “common plant of woodlands” is one of my favorite sights in the spring. The first flowers on wild geranium (Geranium maculatum) usually appear in late April or early May in central Iowa. Occasionally known as spotted geranium or cranesbill, this species is native to most of North America east of the Rocky Mountains. It can thrive in a variety of habitats–“floodplain and upland woodlands, savannas, meadows in wooded areas, semi-shaded seeps, and rocky glades”–and makes a “wonderful shade garden plant.”

Since Bleeding Heartland’s Iowa wildflower series began in 2012, I’ve had an editorial bias toward native plants. But occasionally I have covered non-native species. Last weekend, I saw large stands of poison hemlock blooming in ditches and near railroad tracks. I haven’t seen wild parsnip flowering yet, but that will happen anytime now.

Today’s featured wildflowers are often confused with the native Prairie phlox. But those bright pink flowers have five petals, while blossoms of the European invader Dame’s rocket (Hesperis matronalis) have four.

Some native plants are difficult to distinguish, but bellwort (Uvularia grandiflora) is unmistakable when it’s blooming. Often known as large-flowered bellwort, this species is native to most of North America east of the Rocky Mountains. Its hanging, yellow flowers usually appear in April or May in central Iowa.

If you venture into the woods or along a wooded trail over the Memorial Day weekend, you will have a good chance of spotting the blue-violet or reddish-purple flowers on this native plant. Sweet William usually begins blooming in April, but I didn’t see any flowers this year until May. Also known as wild blue phlox or woodland phlox, this species is native to most of North America east of the Rocky Mountains.

What appear to be five petals on each flower are actually lobes. I believe all of the enclosed photographs show the subspecies Phlox divaricata laphamii, which “has a more western range,” according to the Illinois Wildflowers website. A subspecies called Phlox divaricata divaricata has lobes with notched tips and is generally found in Indiana or to the east.

The Virginia bluebells are fading fast in my corner of central Iowa, but the pink blossoms of spring beauty are still prevalent, along with Jack-in-the-pulpits and striped white violets. May apples (umbrella plants) are near their peak, and the first blossoms of sweet Cicely and Aunt Lucy are starting to appear. Virginia waterleaf won’t be far behind.

I’ve wanted to write about today’s featured wildflowers since Eileen Miller pointed them out near a trail in Dolliver Memorial State Park three years ago. In 2016 and 2017, I looked in vain for colonies of Violet wood sorrel (Oxalis violacea) on my spring walks through wooded areas. Fortunately, Marla Mertz and Lora Conrad have generously shared their photographs of this “delicate” plant, with five-petaled flowers that can be lavender or pink or purple. You may be lucky enough to find these blooming in woodlands or moist prairies during the next several weeks. The species is native to most of the U.S. other than a handful of states west of the Rocky Mountains.

Luther College Associate Professor Beth Lynch educates the Bleeding Heartland community about a rare early spring wildflower. For those who missed it, I highly recommend her post about witch hazel from last October. -promoted by desmoinesdem

One weekend in early April the tourists showed up in town. They were thicker than flies around here. I’ll admit that most of them were here for a new beer release at one of the local breweries, but I also spotted some wild plant tourists tromping around the woods in search of skunk cabbage.

Skunk cabbage is not the first plant to bloom each spring. That award almost always goes to the silver maple trees. And, it is certainly not as cute as the pussy willow buds. So, why are the tourists coming to see skunk cabbage in the mucky swamps around northeastern Iowa?

The seventh year of Bleeding Heartland’s wildflower series is kicking off later than planned. Early spring wildflowers typically would have come and gone in central Iowa by the beginning of May, but an extended cold spell in March and April pushed everything about a month behind schedule.

Follow me after the jump for a sampling of wildflowers you might see during the coming week along Iowa trails or in woodlands. I took all of the enclosed pictures within the past few days near my Windsor Heights home, except for the last photograph, taken last May in Dolliver Memorial State Park (Webster County).

The sixth year of Bleeding Heartland’s wildflowers series was the most rewarding for me. I learned to identify several “new” native plants, captured a few flowers I’d been hoping to feature for years, and showcased more work by guest photographers than ever before.

I enclose below links to all 32 editions of Iowa wildflower Wednesday from 2017, with one picture from each post. Please let me know if you are interested in contributing to this series next year, especially if you have good photographs of species not covered before at this site.

Bleeding Heartland published 140 guest posts by 81 authors in 2016, a record since the blog’s creation in 2007.

I’m happy to report that the bar has been raised: 83 authors contributed 164 guest posts to this website during 2017. Their work covered an incredible range of local, statewide, and national topics.

Some contributors drew on their professional expertise and research, writing in a detached and analytical style. Others produced passionate and intensely personal commentaries, sometimes drawing on painful memories or family history.

For the sixth straight year, I’m wrapping up my weekly wildflower series with asters, which are often among the last native plants blooming around Iowa. This installment is special, though, because Phil Specht shared photographs of asters growing on his property in Clayton County.

Phil has been “running a grass-based, rotationally grazed dairy” for decades. His farm became a “working ecosystem” supporting a phenomenal number of grassland birds, thanks to the diversity of plants and insects. You can learn more about his pasture management practices by listening to this podcast produced by the Land Stewardship Project or Phil’s interview with Practical Farmers of Iowa.

Asters can be notoriously difficult to distinguish from one another. Phil made educated guesses about some of the plants pictured below but would welcome help with the IDs. He believes “most of northeast Iowa’s native species are represented”; “The farm borders the woods and has a little soil that is of prairie origin, so a wide range of habitat.”

Iowa wildflower Wednesday will return during the spring of 2018. The full archive links to photographs of approximately 170 native plant species. That number will hit 200 sometime next year.

Finally, I want to wish the Bleeding Heartland community a happy Thanksgiving and express my gratitude to all who stop by. I’m especially thankful for the photographers who allowed me to publish their work during 2017: Phil Specht, Eileen Miller, Lora Conrad, Wendie Schneider, Beth Lynch, and Katie Byerly.

Now, enjoy some of Clayton County’s lovely asters.

Before Bleeding Heartland’s wildflower series goes on winter break, let’s revisit a late summer bloomer. Today’s featured plant is one of four native species in the Silphium branch of the aster family. (The others, which also have yellow composite flowers, are cup plant, compass plant, and rosinweed.)

Prairie dock (Silphium terebinthinaceum), sometimes known as prairie rosinweed, is among the tallest plants on the tallgrass prairie. The U.S. Department of Agriculture lists Iowa as part of its native range. My understanding is that while prairie dock is common throughout Illinois, it doesn’t really belong in most parts of Iowa. However, I’ve seen it in several Des Moines area prairie plantings, where it blooms in August and September.

According to the Illinois Wildflowers website, prairie dock tolerates drought and “rocky or gravelly soil” well. Though “rather slow to develop,” this “long-lived plant” is “very reliable and nearly indestructible when mature.”

I’ve never felt more depressed working on a wildflowers post than I did while putting the finishing touches on the November 9, 2016 edition of Iowa wildflower Wednesday.

Yesterday’s elections around Iowa and the country put me in a sunnier frame of mind, so today I am featuring the bright yellow flowerheads of wingstem (Verbesina alternifolia).

This member of the aster family is native to most states east of the Rocky Mountains. In Iowa, wingstem typically blooms in the late summer and early fall. Although these plants are sometimes called yellow ironweed, they look nothing like the bright pink or purple ironweed often seen along Iowa roads and trails during the summer.

I’m thrilled to share another talented photographer’s images of a native plant I’ve never seen. Wildflower enthusiast Katie Byerly found these plants growing in Rock Falls (Cerro Gordo County) in September. Experts in the Iowa Wildflower Report Facebook group confirmed her identification of Riddell’s goldenrod (Oligoneuron riddellii), an uncommon species mostly found in Midwestern states and a couple of Canadian provinces.

The scientific name used to be Solidago riddellii, but Leland Searles explained to me, “The genus was changed to Oligoneuron for Riddell’s and Stiff Goldenrods (O. rigidum). They are unlike genus Solidago [most other goldenrods] in several ways.”

Katie went back to Rock Falls a few days ago, hunting for witch hazel after reading Beth Lynch’s post here last week. She had also hoped to find some Riddell’s goldenrod gone to seed. Alas, “the county mowed it up.” It happens. Fortunately, she captured plenty of beautiful shots earlier in the fall.

Many thanks to Luther College Associate Professor Beth Lynch for adapting and sharing an article and photographs she first published in November 2013. I had no idea witch hazel was native to Iowa. Steve Peterson alerted me to Beth’s work and shared some of his own pictures of witch hazel blooming in Winneshiek County. I enclosed those at the end of this post. -promoted by desmoinesdem

TINY JOYS OF A BOTANIST

I write to share with you one of my tiny joys of late fall. I took this photograph during the first week of November. What is it? A twig with some leaves, right? Look again. What are those yellow stringy things hanging from the twig? Spiders? Whiskers? Look closely.

These are the bright yellow petals of the witch hazel flowers. Think about it: flowers blooming in November! Every fall when most of the leaves have dropped from the trees and the sun is weak, I look for these cheery little flowers on the witch hazels. They bring a bit of warmth to the cold dark days when I seem to need it most. Tiny joy, indeed.

Some native plants are unmistakable, but nailing down the ID on today’s wildflowers has been a challenge. When I first photographed a large colony of these plants on Mike Delaney’s restored prairie in Dallas County, I assumed they were sawtooth sunflowers (Helianthus grosseserratus) because of the serrated leaves. However, John Pearson of the Iowa Department of Natural Resources commented in the Iowa Wildflower Report Facebook group, “This may be Prairie Sunflower (Helianthus pauciflorus), note reddish disc flowers. The long, leafless upper stems, however, remind me of Western Sunflower (H. occidentalis).” Leland Searles, another expert on native plants, mentioned that “sunflowers can be confusing.”

I ruled out western sunflower for a couple of reasons. Mike collected the seed that spawned this colony at Tipton Prairie, a never-plowed patch of land in Greene County in the northwestern quadrant of Iowa. But western sunflower (sometimes called fewleaf sunflower) is primarily found in the eastern part of the state. In addition, several sources confirm the central disk florets on western sunflower flowerheads are yellow. Most of the flowerheads on these plants had reddish centers, which is typical for prairie sunflowers.

Mike thought the plants might be giant sunflowers (Helianthus giganteus), but the central disk florets on that plant are darker yellow. Also, there can be more than one flowerhead at the top of the upper stems on giant sunflower plants. These plants had one flowerhead per stem, another characteristic feature of prairie sunflowers. Finally, the upper part of the stems on Mike’s plants had no leaves. Giant sunflower plants have leaves on the upper stems.

So, I’m calling these prairie sunflowers. Sometimes known as stiff sunflowers, Helianthus pauciflorus plants are native to most of the U.S. and Canada. I haven’t seen them anywhere other than on Mike’s land. Next year I hope to visit Tipton Prairie in the late summer or early fall, when they would be blooming. UPDATE: After I published this post, Mike told me he didn’t find any of these at Tipton Prairie this year, but he did find them in the “Rippey strip,” a narrow patch of native prairie several miles long next to the 144 Diagonal road near Rippey in Greene County. He believes he must have collected the original seed from the Rippey area.

Thanks to Lora Conrad for sharing her photographs and describing this colorful plant. I had no idea wild poinsettia was native to Iowa. -promoted by desmoinesdem

How would you like to have a plant with fiddle-shaped shiny green leaves with brilliant red or orange-red at the center on the top leaves, showing off for months?

I’m pleased to share more of Wendie Schneider’s photography today. Last month Wendie gave me permission to publish her pictures of round-headed bush clover. She found today’s featured plant in a restored Story County prairie as well.

Bottle gentian (Gentiana andrewsii) is native to much of the northern U.S. and Canada, but not widespread. Sometimes known as Andrew’s gentian, it thrives in wet habitats: “moist black soil prairies, openings in floodplain forests, thickets, fens, and swampy areas near bodies of water.”

Like its relative downy gentian, bottle gentian typically has blue or purple flowers, though the blossoms can be pink or white. The distinguishing feature of this plant: its flowers stay closed even at the peak of the blooming period, inspiring the alternate common name closed bottle gentian.

This week’s featured plant is far less showy than the brightly-colored Jerusalem artichoke or jewelweed, which bloom around the same time. However, it attracts a wide variety of pollinators and tolerates drought “better than most plants in the tallgrass prairie,” a plus after this unusually dry Iowa summer.

False boneset (Brickellia eupatorioides) is native to most of the U.S., except for New England and the states west of the Rockies. I took all of the enclosed pictures at a prairie Mike Delaney has been restoring on farmland he bought in Dallas County during the late 1980s.

Although Jerusalem artichoke (Helianthus tuberosus) has nothing to do with the historic city in the Middle East, I thought it would be appropriate to feature these late summer wildflowers on the eve of the Jewish new year, Rosh Hashanah.

Why are these plants, native to most of North America, called Jerusalem artichoke? One theory: “The Jerusalem part of the name probably came from a mispronunciation of “girasole,” which is Italian for ‘sunflower.’” During the 17th century, European explorers found what had been “an important food plant for native Americans” for centuries and brought tubers back to the European continent.

The Missouri Botanical Garden’s website notes,

Plants are still grown today for harvest of the tubers which begins about 2 weeks after the flowers fade. Each plant typically produces 2-5 pounds of tubers per year. Raw tubers have a nutty flavor. Tubers may be grated raw into salads, boiled and/or mashed somewhat like potatoes, roasted or added to soups. Unlike potatoes, tubers do not contain starch. They do contain inulin which converts into fructose which is better tolerated by people with type 2 diabetes than sucrose.

Some people find the taste of the tubers (called “sunchokes”) similar to artichokes. If you decide to grow these plants, be aware that they can spread aggressively and “are difficult to remove from the garden. Tiny pieces of tuber left in the soils will sprout.”

Jerusalem artichokes are blooming now near many Iowa trails and roadsides. I took all of the enclosed pictures on trails that run along the banks of North Walnut Creek in Windsor Heights or Walnut Creek in Des Moines.

Ever since I featured a relative of this week’s featured wildflowers three years ago, I’ve been on the hunt for Jewelweed (Impatiens capensis). Sometimes called orange jewelweed or spotted touch-me-not, this plant is native to most of the U.S. and Canada.

Jewelweed thrives in wet habitats: “moist woodlands, partially or lightly shaded floodplains along rivers, edges of woodland paths, swamps, seeps and fens, and roadside ditches.” Anecdotally, less of it is blooming in Iowa this year, due to our unusually dry summer. But a reader tipped me to a large colony of these bright orange flowers at the edge of Greenwood Pond in Des Moines.

Good fortune struck this week. The talented photographer Wendie Schneider shared some of her wildflower pictures from a Story County prairie, and one of the star attractions was a plant I’ve been meaning to feature in this series for years.

Round-headed bush clover (Lespedeza capitata) is native to most of North America east of the Rocky Mountains. Sometimes known as rabbit foot or roundhead lespedeza, its flowers are not nearly as “showy” as other late summer prairie attractions, such as blazing star or compass plant or even ironweed. Nevertheless, Wendie told me that round-headed bush clover is one of her favorites: “I am a sucker for anything with a strong silhouette.”

According to the Illinois Wildflowers website, this plant “adds nitrogen to the soil, and is easy to grow” in sunny conditions. It can thrive in different types of soil and attracts many pollinators.

I love the story behind this week’s featured plant. Sweet coneflower (Rudbeckia subtomentosa), sometimes called sweet black-eyed Susan, is native to more than a dozen states, including Iowa. But this variant of sweet coneflower has a much more limited range in the wild. It’s named for Henry Eilers, the retired nurseryman who found it “in a railroad prairie remnant in Montgomery County, Illinois.”

Rare plants often grow in the long strips of never-plowed land between rural roads and railroad beds. Next year, I hope to spend some time scoping out one Iowa railroad prairie remnant: the “Rippey strip” along the 144 Diagonal near Rippey in Greene County.

I’d never heard of “Henry Eilers” sweet coneflower before finding these plants in one of the flower beds outside the Greater Des Moines Botanical Garden, between Robert D. Ray Drive and the John Pat Dorrian Trail in downtown Des Moines.

We all have our biases, and one of mine is to focus on native plants for this blog’s wildflower series. Over the last six years, Iowa wildflower Wednesday has featured approximately 160 species, only seven of which are non-native. But after Lora Conrad contributed a stunning post on Deptford pink (a European plant) in June, I decided to take some pictures of another beautiful plant that has become naturalized here.

You don’t need to venture into a high-quality habitat to find today’s featured plant. Ironweed (Vernonia fasciculata) can thrive on disturbed ground and is a common sight along Iowa roads in July and August. I took about half the enclosed pictures on a restored prairie in Dallas County and most of the others after pulling over to take a closer look at ironweed growing near the shoulder of Iowa Highway 44.

Sometimes known as prairie ironweed, common ironweed, smooth ironweed, or western ironweed, this species is native to about half the U.S., including all of the upper Midwest and plains states.

At the Iowa State Fair yesterday, I chatted with a reader who enjoys my occasional wildflower posts on Twitter @desmoinesdem. Check out this thread for pictures of more than two dozen wildflowers you might find see around Iowa in early August. Here are a few plants I recently found blooming along a wooded trail. This past weekend, I briefly escaped from the Charlottesville ugliness with a thread spotlighting red, white, or blue American wildflowers.

The common name for today’s featured wildflowers comes from a doctor who “prescribed the plant as an effective laxative.” Some American Indian tribes used the plant medicinally long before Dr. Culver was on the scene in the 18th century, but in a time-honored tradition, our culture didn’t give them the credit for discovering its properties.

Culver’s root (Veronicastrum virginicum) is native to most of North America east of the Rocky Mountains. I’ve never heard anyone call this plant by any other name, but apparently it is sometimes known as Black root or Bowman’s root.

It “tolerates most soils” and “full sun to partial shade,” so “can make an excellent back border specimen in the home garden.” Culver’s root flowers attract many kinds of pollinators, including bees, wasps, butterflies, and moths.

I took all of the enclosed photographs on a restored prairie in Dallas County.

Late summer wildflowers are coming on strong across Iowa. During the past three weeks, I’ve seen the first flowers of 2017 on brown-eyed Susan, common evening primrose, goldenrod, ironweed, cutleaf coneflower, common sneezeweed, white snakeroot, yellow jewelweed, and even New England aster, which usually appears later and continues to produce flowers until the first frost.

Today’s featured plant is nearing the end of its blooming period for the year. Winged loosestrife (Lythrum alatum) can be found in a variety of wet habitats, such as “moist black soil prairies, marshes, fens, borders of lakes and ponds, areas along rivers and drainage ditches, and low-lying ground along railroads.” Sometimes called winged lythrum, this species is native to most of North America from the Rocky Mountains to the east coast.

I took all of the enclosed photos between late June and late July on lower ground in the prairie restoration area along the Windsor Heights trail, behind the Iowa Department of Natural Resources building on Hickman Road.

Note: winged loosestrife can be confused with purple loosestrife (Lythrum salicaria), which is “now ranked among the most highly problematic invasive species in North America.” At the end of this post I’ve included two pictures of purple loosestrife. If this attractive plant is growing on your property, I recommend pulling it up.

Sharing Eileen Miller’s photographs is always a treat, especially when she has captured wildflowers I’ve never seen. Common arrowhead, also known as broad-leaf arrowhead or duckroot, can be found across most of the U.S. and Canada.

Of the more than 150 native plants featured for Iowa wildflower Wednesday since 2012, only a few species have separate male and female flowers: bur cucumber, early meadow rue, and purple meadow rue. Thanks to Eileen, we can add arrowhead to that short list today. She wrote all of the text below.

July is a fantastic month for wildflower-spotting in Iowa. In addition to the many plants I mentioned in last week’s post, within the past few days I have seen the first blossoms of 2017 on common evening primrose, blue vervain, and cutleaf coneflower. Near the Windsor Heights trail, I also found two species I don’t recall seeing in past years: monkey flower and catnip. I hope to feature them on an upcoming Wednesday, along with Culver’s root and Joe Pye weed, which are also blooming now in many natural areas.

I took most of the pictures enclosed below in late May at Tipton Prairie in Greene County. Prairie phlox (Phlox pilosa) typically blooms in the late spring or early summer in Iowa. If you see flowers resembling it during July or August, you are probably looking at a cultivar adapted from this species.

Native to much of the U.S. east of the Rocky Mountains, this plant is also known as downy phlox or fragrant phlox. Its favored habitats “include moist to mesic black soil prairies, rocky open forests, Bur Oak savannas, sandy Black Oak savannas, limestone glades, thickets, abandoned fields, and prairie remnants along railroads.”

According to the Minnesota Wildflowers website, prairie phlox “does well in a garden, in sunny, sandy soil.” The flowers attract a wide variety of pollinators and sometimes ruby-throated hummingbirds. In Wildflowers of the Tallgrass Prairie, Sylvan Runkel and Dean Roosa wrote, “The Meskwaki made a tea of the leaves and used it as a wash for treating eczema. The same sort of tea was drunk to cure eczema and to purify the blood at the same time. Also, the root was used with several other unspecified plants as part of a love potion.”

Summer wildflowers are coming on strong now. On native or restored prairies, you may find cup plants or compass plants in bloom, along with yellow coneflowers, purple coneflowers, rattlesnake master, blazing star, black-eyed Susan, partridge pea, and several kinds of milkweed, including common, swamp, butterfly, or whorled. Along wooded trails, the purple, star-shaped blossoms of American bellflower are a frequent sight.

This week’s featured plant typically starts blooming in the late spring; in most parts of Iowa, the flowers are gone by July. Canada anemone (Anemone canadensis) is also known as meadow anemone, round-leaf thimbleweed, or windflower. This member of the buttercup family is native to most of North America, except for states in the deep South or west of the Rocky Mountains. It can thrive in a range of usually wet habitats, such as “moist prairies, sedge meadows, openings in floodplain woodlands, woodland borders, banks of streams, and swampy areas.” I took some of the enclosed pictures along bike trails in Des Moines and Clive and others on lower ground at the Tipton Prairie in Greene County.

According to the Minnesota Wildflowers website, Canada anemone “can form sizable colonies via spreading rhizomes.” The Friends of the Eloise Butler Wildflower Garden site advises, “In the home garden it can make a good ground cover beneath trees and shrubs but in a restricted setting it needs control due to its spreading habit. For full flowering potential, it needs a mostly sunny area.” Likewise, the Lady Bird Johnson Wildflower Center’s site notes that this plant “can become quite aggressive in too favorable conditions.”

Although today’s featured plant is native to most of North America east of the Rocky Mountains, I’d never seen Prairie redroot (Ceanothus herbaceus) before my first visit to Tipton Prairie in Greene County. Sometimes known as narrow-leaved New Jersey tea, inland New Jersey tea, Jersey tea, or simply redroot, this species thrives in relatively dry habitats, especially “upland woods, prairies, barrens.”

I took all of the enclosed pictures at Tipton Prairie, a never-plowed, four-acre “unique remnant,” during the last week of May. Prairie redroot flowers “about a month earlier” than its relative, New Jersey Tea (Ceanothus americanus). I’ve been told that in Iowa, New Jersey tea plants rarely bloom before June, while redroot typically blooms in May.

Fun fact: Ceanothus species “can fix nitrogen from the atmosphere.”

Thanks to Lora Conrad for sharing these gorgeous pictures. -promoted by desmoinesdem

One summer about 15 years ago, I was walking a path at the Pioneer Ridge Nature Center near Ottumwa and saw among the green plants one stunningly bright, tiny pink flower. Finding out what it was took years! It was not listed in any of the wildflower reference books I had at the time. After seeing more of the tiny bright flowers over the years and then obtaining internet access to wildflower databases, my efforts produced a name and its origins. The brilliant little Deptford pink (Dianthus armeria) is indeed wild, naturalized and, according to uswildflowers.com, is found sprinkled about in 47 of the 50 states—but it is not native to North America. It’s from Europe and is fairly common in western and central Europe but in decline in England.

Its name came from a case of mistaken identity by a 17th century botanist who described another Dianthus that was common around Deptford, England at the time.

For years, I thought today’s featured plant was a European invader, but cow parsnip (Heracleum maximum) is native to most of the U.S. and Canada.

Sometimes known as common cowparsnip, these plants are easy to spot in the late spring and early summer, in part because of their large clusters of small white flowers. They also tend to be taller than anything growing nearby. (By the late summer, other woodland plants may reach similar heights.) Cow parsnip “can be found in both high quality natural areas and disturbed habitats,” but I’ve mostly seen them in the woods. I took most of these pictures near trails in Des Moines and Clive in early June.

Cow parsnip is “the native counterpart to the highly invasive non-native Giant Hogweed.” It grows taller than the non-native wild parsnip, which has yellow flowers and should be avoided unless you want to experience a horrible blistering rash.

Today’s featured plant was a new addition to my “life list” during a recent visit to Tipton Prairie in Greene County. Yellow star grass (Hypoxis hirsuta), sometimes known as common goldstar, is native to most of North America east of the Rocky Mountains. I’d seen pictures of the small yellow flowers in books and on the Iowa Wildflower Report Facebook group, but I don’t think I had ever seen one in person until one of my companions called me over to a slope near the highest point of the four-acre prairie.

I’m excited to publish another series of photographs by Eileen Miller, who has contributed about a dozen spectacular editions of Iowa wildflower Wednesday over the years. For her first guest post here in 2017, she chose to feature Alumroot (Heuchera richardsonii) in the family Saxifragaceae, which she describes as “an intriguing native, perennial wildflower of tall grass prairies.”

Eileen took all of the photographs enclosed below in April at Tipton Prairie, a 4-acre virgin prairie in Greene County. I took the picture at the top of this post during my first-ever visit to Tipton Prairie last month.

June is a perfect time to be out in nature, but a couple of cautionary notes: be sure to put on insect repellent if you go looking for wildflowers in Iowa woods, prairies, or meadows. Also, watch where you step, because 2017 seems to be a banner year for a few dangerous plants: poison ivy, poison hemlock, and wild parsnip. I don’t know whether the mild winter or the timing of the spring rains were responsible.

After last week’s rare and spectacular featured plant (Shooting star), Iowa wildflower Wednesday returns today to the lowly and commonplace. Aunt Lucy (Ellisia nyctelea), also known as Waterpod, is native to most of the U.S. and Canada. Like wild chervil, it doesn’t stand out among other plants that bloom around the same time, so you might not notice its flowers or fruit. The Illinois Wildflowers site says of this plant,

Aunt Lucy is an oddball member of the Waterleaf family. It is not very showy and often omitted from many wildflower guides. Aunt Lucy occurs in two quite different habitats: deciduous woodlands and disturbed areas where the ground is bare or lightly mulched. In the former habitat, it is one of our native spring wildflowers, while in the latter habitat it is a minor weed of nurseries and bare open ground in cities.

I took most of the pictures enclosed below near my home in Windsor Heights. Lora Conrad, a talented photographer and wildflower enthusiast, kindly gave me permission to post a few of her pictures, taken near the Des Moines River in Van Buren County.

Until this month, I had never seen today’s featured wildflowers “in real life.” Shooting star (Dodecatheon meadia) is as eye-catching as last week’s wild chervil is unobtrusive. Also known as prairie shooting star or pride of Ohio, the plant is native to more than 20 states east of the Rocky Mountains, but it is rarely seen outside “high-quality habitats” including prairies, upland forests, and fens.

The Illinois Wildflowers and Minnesota Wildflowers websites have botanically accurate descriptions of shooting star foliage, flowers, and seed capsules. I took all of the enclosed pictures at Rochester Cemetery in Cedar County in early May. This never-plowed patch of prairie is well worth a special trip or at least a short detour if you’re traveling along nearby I-80.
