For this post-primary election edition of Iowa wildflower Wednesday, I asked all of Iowa’s Democratic nominees for federal or statewide offices about their favorite wildflowers.

The candidates could choose any flowering plant. It didn’t have to be a native species or one that tends to bloom in Iowa around this time of year.

I’m presenting the wildflower choices in the same order the candidates appeared on the Iowa Secretary of State’s 2022 primary candidate list.

Lora Conrad features a native perennial at different stages of development.

Great Waterleaf aka Appendaged Waterleaf (Hydrophyllum appendiculatum) is one of only two native Hydrophyllum species in Iowa. The other is Virginia Waterleaf (Hydrophyllum virginianum), which Bleeding Heartland featured here.

Great Waterleaf is a native perennial that thrives in partial shade in rich woodlands. Most photos enclosed below were made on a north facing slope of wooded land just above the Des Moines River in Van Buren County. Others were made in a similar site in Lee County. According to BONAP, it is found more in the eastern two-thirds of Iowa.

Join Lora Conrad for a walk through the Croton Unit of Shimek State Forest to photograph and identify plants growing in this “premier woodland wildflower location.”

“Shimek State Forest is located in Lee and Van Buren counties in southeast Iowa. The forest served as a base for the Civilian Conservation Corps (CCC) in the 1930s and 1940s, where they planted thousands of acres of hardwoods and conifers for demonstration purposes. Named after early Iowa conservationist Dr. Bohumil Shimek, the forest offers bountiful outdoor recreation opportunities… ”

So goes the Iowa Department of Natural Resources’ understated introduction to Shimek State Forest which is 9,448 acres spread across five forest units.

I’m kicking off the eleventh year of Bleeding Heartland’s wildflower series a little later than usual, for two reasons. First, unusually cold weather in March and April delayed many plants’ blooming period by several weeks.

In addition, I severely fractured my ankle in January, requiring surgery, ten non-weight-bearing weeks, and ongoing physical therapy. Although I’m getting around with a cane now, I don’t walk well on uneven ground, which limits my wildflower spotting.

The upshot is that I will probably rely on guest authors and photographers even more than last year. Please let me know if you have pictures to share, especially of plants I haven’t featured yet. (Click here for the full archive, featuring more than 200 species.) Some spring or early summer bloomers which have yet to be introduced to Bleeding Heartland readers include Jacob’s ladder, false Solomon’s seal, and Four o’clock.

I also welcome guest posts showcasing a favorite trail, park, or nature area, with pictures of different plants that may be blooming on a given day or weekend. Restoration success stories like last year’s contributions by Kenny Slocum and Grinnell College students are also well received.

This week’s featured plant is a shrub or small tree. Wild plum (Prunus americana) is native to most of the U.S. and Canada. Also known as American Red Plum, these plants can thrive in a range of habitats, from roadsides to woodlands to open fields or prairies. The Illinois Wildflowers and Minnesota Wildflowers websites have botanically accurate information about various parts of the trees.

Editor’s note from Laura Belin: I’m interrupting the winter hiatus of Bleeding Heartland’s wildflowers series to bring you some lovely images by a new guest photographer, Paul Laning. He first shared these pictures in the Iowa wildflower enthusiasts Facebook group, which has remained active this winter.

I’ve had professional training in photography and design and been taking pictures since 1978. I take many nature photographs, but hoar frost is one of my favorites. I hope you enjoy my art.

I took the first five pictures with my cell phone near Buffalo Center (Winnebago County). I shot the last with a Canon EOS in Clear Lake.

It’s hard to believe Bleeding Heartland’s wildflowers series is ten years old. I could not have made it through this year without assistance from guest authors and photographers. Katie Byerly, Lora Conrad, Tommy Hexter and Jacy Highbarger, Elizabeth Marilla, Marla Mertz, Bruce Morrison, Leland Searles, Kenny Slocum, and Patrick Swanson wrote a total of fifteen posts during 2021. They and others (Kim El-Baroudi, Janette Foust, and Mary Riesberg) also contributed photographs to several of my posts.

One of my new year’s resolutions is to visit more state parks or wildlife preserves, and get out to Mike Delaney’s restored Dallas County prairie more regularly. The last couple of years I haven’t gone wildflower hunting as often as I did before the pandemic.

This series will return sometime during April or May of 2022. Please reach out if you have photographs to share, especially of native plants I haven’t featured yet. The full archive of more than 250 posts featuring more than 220 wildflower species is available here.

For those looking for wildflower pictures year round, or seeking help with plant ID, I recommend the Facebook groups Flora of Iowa or Iowa wildflower enthusiasts.

As Thanksgiving approaches, I’m wrapping up the tenth year of Bleeding Heartland’s wildflowers series. I’m so grateful to the guest authors who contributed posts and photographs this year: Katie Byerly, Lora Conrad, Tommy Hexter and Jacy Highbarger, Elizabeth Marilla, Marla Mertz, Bruce Morrison, Leland Searles, Kenny Slocum, and Patrick Swanson.

Iowa wildflower Wednesday will return sometime during the spring of 2022. Please let me know if you would like to write about any one plant, or group of plants that thrive in a similar habitat, or special place or trail. Anyone on Facebook can connect with nature lovers year round in the Iowa wildflower enthusiasts group, which now has more than 5,300 members.

To close out this year’s series, Lora Conrad contributed nine photographs of berries or berry-like fruit that can be found on plants in Van Buren County at this time of year. All but one are native to Iowa.

Wildflowers were a gateway to Mycophilia for me. Until very recently, I could only name and identify the most famous mushrooms I might wish for while walking around looking at wildflowers: Morel, Chanterelle, and Chicken of the Woods.

This post is dedicated the members of the Prairie States Mushroom Club, who warmly welcomed me into this bottomless new pastime during the pandemic, and who have very generously taught me many new things about the fungal biodiversity of Iowa–in particular Sarah, Glen, Roger, Marty, and Dean. These folx spotted some of the mushrooms pictured below. There are no additional forays planned for this year, but all fascinated newbies (as well as those with years of expertise) are welcome to join the club again next spring.

This post is also dedicated to the vigilant, patient, and devoted administrators of the Iowa Mushrooms Facebook page, total strangers who have been great teachers, helping me identify so many scrappy little specimens at all hours of the day and night! Impassioned beginners desperately need people like them. Luckily, it appears that the mushroom-loving community includes many genius laypeople, as well as quite a few very cool scientists.

Pictured below are ten of my favorite mushrooms found and photographed in southeast Iowa this summer and fall, with friends and often with my 3-year-old daughter. I have included a few of her recent mushroom drawings at the bottom of the post.

When my wife and I moved to our little acreage in northwest Iowa nearly 20 years ago, I had already experienced a lifetime of love and reverence for the Landscape. I can still remember my summers as a youngster on the Des Moines River, which I lived above in Fort Dodge, and almost daily hikes down the railroad tracks to a friend’s farm west of town – where the Lizard Creek spread below their “night pasture”, as they called it…and met downstream with the north fork where the Chicago Northwestern track crossed the waterway’s junction.

The hillsides above the creek were favored respites to lay on in the summer sun and dry off after a swimming hole visit or after wading a good fishing hole; and many times just to watch the valley’s pair of Red-tail Hawks magically hanging in the air high overhead. The views always left me wanting to hold them fast in my memory; it was an emotion I never shook.

I was so sorry to hear that former U.S. Representative Neal Smith passed away on November 2 at the age of 101. Iowa’s longest-serving member of the U.S. House represented Polk County in Congress for 36 years, rising to the third-ranking position on the powerful Appropriations Committee. He had tremendous knowledge and wisdom. Having grown up poor during the Great Depression, he sought to use government to improve people’s lives.

I didn’t know Smith well but I always enjoyed seeing him at Democratic events, most recently at a Polk County or Third District event in 2018. The last time we spoke on the phone was in the summer of 2019, when I was working on a piece about the first passage of the Hyde amendment. At the age of 99, Smith recalled details about that 1976 House floor vote clearly.

Of all the events canceled due to the COVID-19 pandemic, the one I was saddest about was the planned celebration of Smith’s 100th birthday at Drake University in March 2020.

Distinguishing goldenrods is a tricky business, even for plant experts. For this post, I am relying on the insight of Leland Searles. He reviewed a few of my photographs and worked through “the key for genus Solidago” to arrive at Missouri Goldenrod (Solidago missouriensis). Leland ruled out Canada goldenrod “because it has green leaves almost to the ground instead of withered leaves from midstem to base; it appears not to have any hair below midstem; and the compound flower heads are large, larger than I’d expect for Canada Goldenrod.”

You might find Missouri goldenrod in a range of habitats, including “black soil prairies, clay prairies, dolomite prairies, hill prairies, limestone glades, prairie remnants along railroads, and thickets in upland areas.” But I took all of the pictures enclosed below in a drainage area next to a Windsor Heights school parking lot.

As Illinois Wildflowers points out, this species (like most goldenrods) is “easy to grow.” In an open prairie, it may form “large spreading colonies.” But even a few plants (as in the small space I photographed) will likely attract a wide range of pollinators.

Lora Conrad profiles a weedy native plant that favors disturbed ground.

Known variously as American Burnweed or Fireweed or Pilewort, Erechtites hieraciifolius (Senecio hieraciifolius is an earlier synonym) is found throughout Iowa as well as states east of Iowa. The names burnweed and fireweed result from its penchant for occurring in recently burned areas.

Why the other common name? Well, some indigenous peoples extracted oil from the plant and used it to treat piles, also known as hemorrhoids, thus the moniker pilewort.

It is a native summer annual in much of the U.S., as well as Central and South America. With its penchant for disturbed soil, you may see it sprinkled about or exploding in great numbers in recently disturbed soils, replanted prairies, roadsides, open woods, and renovated wetlands. It follows human habitation and disturbance of the soil. While considered “weedy,” it is not invasive. It tends to fade away as new plantings get more established. Despite its obvious appreciation for replanted prairies and native status, it is not listed in the UI “Iowa Prairie Plants” online.

If you’ve walked near the woods or on a shady trail in the late summer or fall, you’ve probably passed by today’s featured plant, but you may not have noticed it. Jumpseed is native to most of the U.S. east of the Rocky Mountains. This member of the buckwheat family thrives in shade or partial shade, especially near woodlands or thickets. It may “be more common in woodlands with a history of disturbance.” Its small flowers don’t attract much attention.

Many plants are known by variety of common names. Oddly, jumpseed seems to have no other common names, but several scientific names refer to the same plant. Illinois Wildflowers explains, “Jumpseed (Antenoron virginianum) has a history of taxonomic instability – scientific synonyms include Polygonum virginianum, Persicaria virginiana, and Tovara virginiana.”

I took all of the pictures enclosed below near my Windsor Heights home in September or October.

After showcasing many native plants last week, I decided to focus today on a non-native member of the mallow family. Flower of an hour (Hibiscus trionum) has spread widely across most of the U.S. and Canada. While many consider it a weed or pest, some people grow it as an ornamental. You may find it near roadsides or in residential yards.

I’ve seen more of these plants than usual this year, because a street improvement project in my Windsor Heights neighborhood tore up a lot of curbs and sidewalks. The disturbed ground was perfect habitat for non-native plants. Like velvetleaf/buttonweed, seeds from flower of an hour “can remain viable in the soil for several years, if not decades,” according to the Illinois Wildflowers website.

Capturing usable photos was more challenging than I expected. I often saw these blossoms while walking my dog. But many times, when I came back later the same day, the flowers were gone. Jackie Carroll explained on the Gardening Knowhow website that flower of an hour “gets its name from the pale yellow or cream colored blossoms with dark centers that only last a fraction of a day and don’t open at all on cloudy days.”

Lora Conrad came to the rescue again with lovely pictures she took in Van Buren County.

Instead of focusing on one plant this week, I’d like to share photographs from my September 12 visit to Mike Delaney’s prairie in Dallas County. Mike’s property has provided source material for lots of Bleeding Heartland posts over the years, most recently this summer’s features on showy tick trefoil and starry campion.

Every time I explore the area, I find something I hadn’t seen before. You’d never guess this land next to the Middle Raccoon River was in corn and beans for decades before Mike spent about 25 years restoring the prairie.

I was excited to find a patch of “new” (to me) wildflowers near the banks of North Walnut Creek a few weeks ago. Since I wasn’t familiar with these small pink flowers, I posted a few photos to the Iowa wildflower enthusiasts Facebook group. Lora Conrad quickly identified the plants as Siberian Cranesbill (Geranium sibiricum).

As the common name suggests, this species originated in Eurasia, not North America. Although I usually showcase native plants for Bleeding Heartland’s wildflower series, today will be one of my occasional exceptions.

Minnesota Wildflowers offered tips for distinguishing Siberian Cranesbill from the similar-looking native Bicknell’s Cranesbill. As Lora explained, the plant I photographed has single flower stalks, is hairy, and blooms in August and September—all signs pointing to the introduced species. The habitat (partial sun, loamy soil, near disturbed ground) is also consistent with where this species often thrives.

Katie Byerly features a delicate plant that blooms in the late summer.

There are more than 400 gentian species globally, with most growing in the mountains in Europe. In Iowa one might be lucky to find seven different species of gentian. Six of those have brilliant bluish purple flowers. Then there is Cream Gentian (Gentiana alba), also called Pale, Plain, or Yellow Gentian. Cream gentian flowers can be an off-white creamy color, or a yellowish white or a greenish white.

No matter what color you find, all flowers share the greenish yellow venation on the petals.

I have a soft spot for native plants that can thrive in some of the least hospitable environments. The natural range of common evening primrose (Oenothera biennis) covers most of North America east of the Rocky Mountains, and you’re as likely to find it by roadsides or in vacant lots as near woodland edges, prairies, or streams. These plants typically start blooming in July, but you may see some flowers as late as October.

Sometimes known as weedy evening-primrose, German rampion, hog weed, King’s cure-all, or fever-plant, common evening primrose has been used medicinally for hundreds of years. Its seeds are used to produce evening primrose oil, which many take for various health conditions. My midwife recommended that I take evening primrose oil toward the end of my first pregnancy to help ripen the cervix.

The roots and parts of the plants are edible as well, though I’ve never tried cooking them. I took most of the pictures enclosed below in Windsor Heights or Urbandale in early September.

I usually visit Mike Delaney’s Dallas County property to check out what’s growing on the prairie he’s been restoring for more than 25 years. But on my last visit, Mike pointed me toward an area in the woods where I could find some lovely wildflowers. I believe this was my first encounter with starry campion (Silene stellata) in bloom.

These distinctive plants thrive in “light shade or partial sun, mesic to dry conditions, and soil containing loam, clay-loam, or a little rocky material,” according to the Illinois Wildflowers website. Favored habitats include “rocky woodlands, wooded slopes, savannas, shaded banks of rivers, meadows near wooded areas, and cemetery prairies.”

I took most of the pictures enclosed below on the wooded slope near Mike’s prairie in late July.

Today’s featured plant is native to North America and has become widespread in Iowa, but is also on our state’s primary noxious weed list. By some accounts, horse nettle (Solanum carolinense) originated in the southeast U.S. and is “adventive” in much of the Midwest. Others say the plant (sometimes called Carolina horsenettle, bull nettle, or devil’s tomato) is native to the prairie that once covered most of Iowa.

Either way, you wouldn’t want to grow horse nettle deliberately. It can be aggressive, especially “in disturbed sites around developed areas,” according to Illinois Wildflowers. It’s also toxic to most mammals, including humans. So if these plants appear on your property, you may want to dig them up to avoid spread.

I took the pictures enclosed below near woodland edges in Windsor Heights, Clive, and Urbandale between late June and late August.

Bloody Run County Park already had a lot going for it when I began working for the Clayton County Conservation Board in 2015. The unassuming 135-acre park outside of Marquette, Iowa has held a special place in the hearts of trout fishermen for decades.

Bloody Run Creek, for which the park is named, is one of Iowa’s few official Outstanding Waters, an Iowa Department of Natural Resources designation reserved for water bodies with exceptionally high quality. The name conjures up evocative imagery of battles won and lost in ages past. Indeed, local folklore offers an array of colorful etymologies and, fact-based or not, they speak to the rugged valley’s longstanding appreciation and respect from the people who know it best.

Unfortunately, it is now ground zero for a modern battle between industrial agriculture and environmentalists.

Tommy Hexter ‘21 and Jacy Highbarger ‘22 wrote this post. The authors are co-founders of Grinnell College’s chapter of Herbicide-Free Campus; Poweshiek Soil and Water Commissioner (former), and student members of Too Much Grass student-initiative at Grinnell College.

In the spring of 2021, a group of excited Grinnell College students, along with faculty and staff, acted on a student initiative called “Too Much Grass” and came together to create a 5,200 square foot prairie in the most prominent location on campus, Mac Field.

In collaboration with the College Center for Prairie Studies and the recently-founded Herbicide-Free Grinnell, chapter of the larger organization Herbicide-Free Campus, Too Much Grass aims to remove unnecessary lawn areas on campus and plant prairie seeds in their place. The hope is to create a place where future Grinnellians for generations to come will loaf through the planting and ponder the meaning of these deep perennial roots in Iowa soil.

In just three months, this project has already sparked interest in another planting on campus scheduled for September.  

I’m excited to write about showy tick trefoil (Desmodium canadense). I’ve wanted to feature these plants for at least five years, but I never caught them the right time. Last weekend I was excited to find many plants blooming next to the Dallas County prairie Mike Delaney has been restoring for more than 25 years.

Also known as hoary tick-trefoil or Canada tick-clover, showy tick trefoil is native to most of the U.S. and Canada east of the Rocky Mountains. A wide variety of pollinators visit its flowers or feed on its foliage.

Although showy tick trefoil flowers are beautiful, you may not want to cultivate them in a garden, because its seedpods are notorious for sticking to clothing or animal fur. According to Illinois Wildflowers, this plant’s preferred habitats “include moist to mesic black soil prairies, moist meadows along rivers, borders of lakes, thickets, limestone glades, and areas along railroads where prairie remnants occur.”

Common Mullein, Great Mullein and Woolly Mullein are all names for the same plant, a non-native weed introduced from Europe in the early 1800s. It has spread so widely that it is now considered naturalized. Common mullein can be found in all 50 states, and even though it is a weed, it is not pesty (at least not in Iowa).

Of all the Iowa wildflowers, this plant has some of the most fun nicknames, including Cowboy Toiletpaper, Quaker’s Rouge, Torch Flower, Flannel Plant, Tinder Plant, and Aaron’s Rod.

If you are a wildflower enthusiast, someone not familiar with common mullein may ask you, “What is that tall fuzzy plant that I saw on the side of the road?”

Although much of Iowa is in drought, one plant that thrives in moist habitats seems to be abundant this year, at least in central Iowa. American germander (Teucrium canadense), also known as Canada germander or wood sage, often grows in “moist thickets, ditches, woodland edges, [or] along streams.” I usually see it blooming by July 4, and the flowering period lasts for at least a month.

According to John Pearson of the Iowa Department of Natural Resources, Teucrium canadense is the only germander species that is native to Iowa. Eight other species of germander are native to North America, and gardeners may grow some of them successfully in our state.

I took most of the pictures enclosed below near North Walnut Creek, which runs through Urbandale and Windsor Heights.

A plant I’d never noticed before showed up on my doorstep (literally) this summer. Once flowers began to appear in late June, I posted a few pictures in the Iowa wildflower enthusiasts Facebook group I created last year. A member of that community quickly identified the mystery plant as American lopseed (Phryma leptostachya).

As the name suggests, American lopseed is native to most of North America east of the Rocky Mountains. These plants can also be found in California. The Illinois Wildflowers website notes that this species (sometimes known simply as lopseed) “prefers a sheltered location that provides light to medium shade, moist to mesic conditions, and a rich woodland soil with abundant organic matter.”

How did these wildflowers suddenly turn up in an area I have watched closely for 20 years? According to ecological consultant Leland Searles, birds may have carried the seed to my yard, or animals may have tracked it in on their hooves or paws.

Lora Conrad reviews nine useful resources for plant identification in Iowa.

Whether you are new to learning about Iowa wildflowers and native shrubs and trees or have been studying them as a hobby for some years, you are sure to see a plant or flower that you just can’t identify. Before posting a question for the experts on your local wildflower or flora Facebook page, you might want to see what you can learn about the plant and determine yourself.

Three types of resources are widely available: plant identification applications for a smart phone, public web pages from authoritative sources, and books. Each source can be useful but not always sufficient.

The purpose of this article is to compare the reference books that have helped me most in identifying plants in the woodlands, prairies, waysides, river banks, and roadsides of Iowa, as well as in my untamed yard. These are recommendations from a determined wildflower enthusiast—not from a botanist. So with that caveat, please read on.

Wildflower love and layperson learning, often nurtured by the wisdom shared on Iowa wildflower Wednesdays, has led to closer looks at lots and lots of plants, and subsequently to my wondering amateurishly at the beings the wildflowers host and nourish–basically bugs I’ve ignored for way too many years!

Many mornings I hike with my daughter. We take pictures, get silly, find mushrooms (and slime molds), stomp around. Her questions are getting much smarter than mine, and if she miraculously naps in the afternoon, I often spend that time learning about flowers and bugs from far smarter folks than I, hoping I will be able to answer her questions when she awakes.

Below are a few things we have wondered about together this spring and summer. If anyone would like to share what they know about these native bug/flower relationships in the comments, add bumble bee IDs, or correct any errors, I very much welcome learning from other enthusiastic Iowans.

Earlier this month marked the first of what I hope to be a more common event in western Iowa: an organized multi-day hike through the Loess Hills. 

Conceived and orchestrated by Golden Hills Resource Conservation and Development (RC&D) and other partners, the Lo(ess) Hi(lls) Trek, as it was called, gave about 30 folks the opportunity to walk a route through and between conservation lands in Monona County. Golden Hills RC&D recently posted an excellent day-by-day synopsis of the LoHi Trek, so I won’t recap the details here.

As a participant, I would like to offer some of my reflections on this journey.  

Today’s featured wildflowers are the opposite of “showy.” If you’ve spent any time in the woods or near woodland edges, you’ve probably walked by these plants without noticing.

Honewort (Cryptotaenia canadensis), sometimes known as Canadian honewort, is native to most of the U.S. and Canada east of the Rocky Mountains. Like bedstraw, wild chervil, enchanter’s nightshade, and Virginia stickseed, honewort plants have tiny white flowers and thrive in shady wooded habitats.

Deer don’t care for honewort plants, but according to the website of the Lady Bird Johnson Wildflower Center at the University of Texas, “Its young leaves and stems may be used as a seasoning like parsley or as a boiled green; the roots may be cooked and eaten like parsnips.” However, “Caution is advised because many similar species of the carrot family are deadly poisonous.” I have never attempted to eat any part of honewort plants. I’ll leave them for the many kinds of insects that are attracted to the flowers or feed on the foliage.

There be dragons out in our Iowa woodlands! Many of us who like to walk the woodland trails and explore are probably familiar with Jack-in-the-pulpits. Jack has a lesser-known cousin. The Green Dragon (Arisaema dracontium) appears to be a tropical, exotic plant with its bloom hidden with surrounding foliage. This fragile plant has been known to be quite rare, but I feel that is changing within our landscape.

The first part of the scientific name comes from the Greek words aris, a kind of arum, and haema, meaning “blood”. Dracontium is from the Latin meaning “of the dragons,” probably because of the deeply divided leaves.  

Green dragon is a native perennial herb and can be found throughout Iowa, except in the northwest. The plants grow in fertile, slightly acidic, and moist soil within shady woodland areas that are protected from livestock.

The photos enclosed below were taken at Cordova Park, on the north side of Lake Red Rock in Marion County along the Karr Trail.

If you’ve walked along a woodland edge or near running water lately, you may have encountered a perennial woody vine that is “very valuable as a source of cover and food to many insects and animals.”

Wild grape (Vitis riparia) is also known as riverbank grape, because it often grows near rivers or streams. According to the Illinois Wildflowers site, it can do well in prairies near woods or water sources and thrives on disturbed ground, such as areas near railroads. Minnesota Wildflowers notes,

Some consider Riverbank Grape a weedy pest, sometimes creating dense masses and smothering other plants and even small trees. Though it can become aggressive along woodland edges and other disturbed areas where seed is spread, it is typically better behaved in the shadier riverbanks and mature forests where it competes well with other forest species.

I took most of the pictures enclosed below along North Walnut Creek in Windsor Heights in late May.

My editorial bias is to feature wildflowers that are native to Iowa or at least to North America. But I make some exceptions for non-native plants that are prevalent here.

Ground ivy (Glechoma hederacea), more commonly known as creeping Charlie, is an invasive species with origins in Eurasia. European settlers brought these plants to this continent, probably for use in creating medicines. According to the USDA’s Forest Service website, this species was reported in Indiana as early as 1856 and in Colorado in 1906, “suggesting its westerly introduction and/or migration did not occur recently.”

Illinois Wildflowers lists preferred habitats: “floodplain forests, semi-shaded areas along rivers, powerline clearances in woodland areas, cemeteries, lawns and gardens, and miscellaneous waste areas.”

Most Iowans who are familiar with creeping Charlie know it as a “common lawn weed problem.” The University of Illinois Extension notes,

Wild ginger (Asarum canadense) is a native wildflower found throughout Iowa. It grows primarily in colonies in moist areas, especially hillsides. Limestone rocks seem to promote excellent growth.

The horsetails and scouring rushes (genus Equisetum) are rather odd plants on the Midwestern landscape, because they look like nothing else. They are related, by their genetic makeup and reproductive means, to the ferns. Occasionally, scouring rushes grow in dense colonies in the roadsides, where their dark green color and parallel vertical growth are a contrast with the other plants on their margins. A few plants manage to rise in the midst of such colonies, but these plants often are very dominant in the space they occupy.

Horsetails and scouring rushes have historical uses for several tasks, and they have provided medicines for some ailments, although those sometimes contradict each other. In general, the medicinal purposes are not backed by scientific evidence – only the testimonials of herbalists and the recorded uses by ethnobotanists who studied small-scale cultural groups in North America and elsewhere.

Yet the frequent occurrence of at least two species makes them deserving of attention as a native plant species.

The tenth year of Bleeding Heartland’s wildflower series kicks off with a plant that’s a common sight in Iowa woodlands, especially in April. Cutleaf toothwort (Dentaria laciniata), also known as toothwort, is native to every state east of the Rocky Mountains.

According to the Illinois Wildflowers website, favored habitats “include deciduous mesic woodlands, floodplain woodlands, wooded bluffs, and upland savannas. The presence of this species in a woodlands indicates that its soil has never been plowed under or subjected to heavy construction activities.”

The site says cutleaf toothwort “can survive some disturbance caused by occasional grazing and less disruptive activities of human society,” but tends to decline when the invasive garlic mustard becomes prevalent. (Now’s a good time to pull up garlic mustard, if the soil is soft and moist. It’s been so dry in central Iowa lately that I’ve found many of the roots break off.)

Most of the photos enclosed below were taken near my Windsor Heights home. Mary Riesberg also shared pictures she took in Hancock County, Illinois, just across the Mississippi River from Lee County.

I had big plans for the ninth year of Bleeding Heartland’s wildflowers series. Most of my ambitions didn’t pan out. I didn’t visit any of my favorite state parks or wildlife preserves and made only one trip to Mike Delaney’s restored Dallas County prairie, a plentiful source of material in the past. I also spent less time on bike trails in 2020, with no farmers market to ride to on Saturday mornings.

Other photographers stepped up to help. Many thanks to those who authored posts (Katie Byerly, Lora Conrad, Beth Lynch, Emilene Leone, Elizabeth Marilla, Bruce Dickerson, and Patrick Swanson) and those who contributed photographs for one of more of my pieces (in addition to the guest authors, Marla Mertz, Sheryl Rutledge, Leland Searles, Julie Harkey, Wendie Schneider, and Don Weiss).

Iowa wildflower Wednesday will return sometime during the spring of 2021. Please reach out if you have photographs to share, especially of native plants I haven’t featured yet. The full archive of more than 250 posts featuring more than 220 wildflower species is available here.

For those looking for wildflower pictures year round, or seeking help with plant ID, I recommend the Facebook groups Flora of Iowa or Iowa wildflower enthusiasts.

“This was my worst year ever for getting out with my camera,” I told a friend in October.

“It’s been the worst year for a lot of things,” she replied.

Most of the wildflower posts I’d planned for this fall never came together. Day after day, I kept finding reasons not to drive to a prairie or go for a bike ride on nearby wooded trails. So instead of closing out this year’s series with my own pictures of late bloomers like asters and goldenrods, I am sharing images of plants that finished flowering months ago. Katie Byerly, also known as the “Iowa Prairie Girl,” gave permission to publish the photographs enclosed below, which she took in Cerro Gordo County in early October.

Iowa wildflower Wednesday will return sometime in the spring of 2021.

As November 8, 2016 approached, I prepared to profile prairie blazing star, which seemed like a fitting way to celebrate the first woman to be elected president.

This year, I was too superstitious to plan for the first post-election Iowa wildflower Wednesday. But now that Joe Biden’s path to 270 electoral votes seems clear, I want to feature one sunflower (plant from the Helianthus genus) that is native to the state in question for every batch of electoral votes Biden flipped.

I live on 25 acres in Appanoose County. Although I’m not able to do it as often as I’d like to, I try to get in some exercise by walking around my pasture and small wooded area that I own. Not a farm, but we do have a couple of horses, and I rent pasture to my Amish farrier so there are sometimes as many as ten horses keeping the grass from getting too tall.  

Anyway, while on a walk a couple of weeks ago I came across what I believe is Lamb’s Ear (Stachys byzantine), also called woolly hedgenettle, in the wooded area of pasture.
