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.

I was walking through Ada Hayden Prairie in Howard County, Iowa, the first time I saw Purple rattlesnake-root (Prenanthes racemosa). Anytime I see a new plant I find myself thinking out loud “I wonder what that is?” But the first time I saw purple rattlesnake-root, sometimes called Glaucous white lettuce, it hadn’t bloomed yet and my wondering was more like “what the in the world is that??!” And maybe a few other words too.

A thought experiment: can I find any flowering plant that is more prevalent and more despised in Iowa than garlic mustard, featured on this website last year?

Yes, I can.

Although autumn officially began this week, much of Iowa is experiencing summer-like weather, so I thought it fitting to feature a native plant that typically blooms from June through August. Wild bergamot (Monarda fistulosa) can thrive on disturbed ground near roadsides as well as in high-quality prairie habitats or woodland edges. Also known as horsemint or bee balm, it is native to almost all of the U.S. and Canada.

You can often find wild bergamot growing along bike trails, and it’s a popular plant for restored prairies and butterfly gardens. Minnesota Wildflowers says of this “excellent garden plant,” “The dried leaves and flower heads are wonderfully aromatic; Bergamot oils have been used in natural healing for centuries.” A closely related plant called Oswego tea “was used as a beverage by the Oswego tribe of American Indians and was one of the drinks adopted by American colonists during their boycott of British tea,” according to the Britannica website.

As other wildflowers are beginning to fade, Rough blazing star (Liatris aspera) is just getting started. Also called tall blazing star, this unbranched, upright plant grows to be between 2 and 5 feet tall, according to Illinois Wildflowers. 

Rough blazing star blossoms in a spike-like arrangement of pink to purple flowerheads up and down the stem. This spike adds wonderful electric rosy purple color to the natural scenescape.

Rough blazing star flowers start blooming at the upper tip of the plant in July. This first photo shows a monarch butterfly getting nutrients from a rough blazing star just starting to bloom.

The overwhelming majority of wildflowers Bleeding Heartland has featured over the past eight and a half years have been native to North America. Occasionally I’ve showcased plants that are widespread in Iowa, even though they originated on other continents.

Rough cinquefoil (Potentilla norvegica) can’t be placed definitively in either group.

Its scientific name and alternate common name (Norwegian cinquefoil) suggest a European origin. But the U.S. Department of Agriculture considers the plant native to most of the country.

While some summer wildflowers are easy to overlook, you can’t miss Trumpet vine (Campsis radicans) when it’s in bloom. Also known as Trumpet creeper, this woody vine is native to most of the U.S. but “can be weedy or invasive.” I haven’t seen it displacing native plants in Iowa, though.

A “favorite of hummingbirds” thanks to its large orange or reddish flowers, trumpet vine easily attaches itself to other plants, fences, or buildings.

I took most of the pictures enclosed below this week in Windsor Heights or Des Moines.

As I child, I pondered the (to me, peculiar) idea that in Victorian times at least some people believed that children should be “seen, but not heard.” Twisting that idea around, there are quite a few plants in Iowa that will rarely be seen, but it’s certainly worth hearing about them.

Several years ago, I profiled witch hazel, which certainly fits in the rarely-seen (at least, in Iowa) category. Today, I bring to you the tiny Iowa golden saxifrage (Chrysosplenium iowense), which by historical accident is named for Iowa, even though it is almost never seen in Iowa.

For the last two summers, I have been working on converting large sections of my home’s yard to native plant space. I’ve been documenting the process both on my own Facebook page, as well as on Casa Leone Gardens. I was invited to write a post about my project for Bleeding Heartland’s wonderful “Wildflower Wednesday” series, and I’m so happy to do so!

Today’s featured plant won’t win any popularity contests. In fact, I know people who rip Virginia stickseed (Hackelia virginiana) out of the ground as soon as they identify it anywhere on their property.

This common woodland species, sometimes just called stickseed, has unimpressive flowers that become irritating burs. The burs spawned the common names beggar’s lice or sticktight. I don’t pull up these plants like I do with garlic mustard, but I keep an eye out for them so my shoes, clothes, and dog don’t end up covered in burs.

Virginia stickseed is native to most of the U.S. and Canada east of the Rocky Mountains. I frequently see it in the woods or near woodland edges. According to the Illinois Wildflowers site, “Stickseed prefers disturbed wooded areas and it is rather weedy.”

I took the pictures enclosed below in Windsor Heights, Clive, or Urbandale.

The flowers of this prairie inhabitant have eluded me for years. Fortunately, I have friends with better timing.

Leadplant (Amorpha canescens) is indigenous to most of the Midwest and plains states, but it’s not one of those native plants you’ll often see along the roadside, like ironweed.

Although leadplant (sometimes called lead plant) is not rare or threatened, I’ve only found it in good-quality prairies, where it “tends to grow in clumps.” The Illinois Wildflowers website validates my experience: “The presence of Leadplant is a sign of high quality habitat. Because of its deep roots, recovery from fire is very good.”

Speaking of which, the Friends of the Eloise Butler Wildflower Garden website notes that “The alternate name ‘Devil’s Shoestrings’ comes from the deep roots which farmers were never able to plough out.” The more common name of leadplant comes from “the whitish or hoary color tinge from the fine leaf and stem hair.”

Some wildflowers are show-stoppers, while others are easily overlooked. A small colony of Enchanter’s nightshade (Circaea lutetiana) has been growing near my home for many years, but I hardly noticed its blossoms until relatively recently. I learned to identify this plant just last fall, thanks to Leland Searles, a walking encyclopedia of Iowa flora.

Sometimes known as Broadleaf enchanter’s nightshade, this plant is native to most of the U.S. and Canada. If you spend time on wooded trails in the summer, you may have passed it many times without noticing. The plants are only one to two feet tall, and their flowers are tiny, one-eighth to one-fourth inch in diameter.

Enchanter’s nightshade thrives in dappled sunlight or shade. The Illinois Wildflowers website notes, “This is one of the woodland wildflowers that blooms during the summer in shaded areas. The flowers of such species are usually small, white, and not very showy.” The same site speculates, “This plant may be less abundant than in the past because of browsing by deer.”

I took most of the pictures enclosed below in Windsor Heights during the first week of July.

In the eight years I’ve been writing about wildflowers on this site, my editorial bias has been toward species that belong in this part of North America. However, I do occasionally feature non-native species that have become naturalized in Iowa. So it is with this week’s plant.

Catnip (Nepeta cataria) originated in Europe, but this member of the mint family can now be found in nearly every part of the U.S. and Canada. Although it is not highly invasive like garlic mustard, it can thrive in many habitats and may spread rapidly in gardens.

In central Iowa, I’ve mostly seen catnip near trails or woodland edges. I took most of the pictures enclosed below during the past week near the edge of the woods where Clive meets Windsor Heights.

If you can stand the heat, early July is an excellent time for wildflower spotting in Iowa. Prairie habitats are exploding in color now, but this week I decided to focus on plants that can often be viewed from the shade at woodland edges.

I took all of the pictures enclosed below between July 1 and July 8 near wooded trails in Windsor Heights, Clive, Urbandale, or West Des Moines.

If you’ve considered introducing native plants to a garden, today’s featured wildflower is for you. Wild petunia (Ruellia humilis) is “quite adaptable, tolerating full or partial sun, moist to dry conditions, and practically any kind of soil,” the Illinois Wildflowers website writes.

Sometimes known as fringeleaf wild petunia, this species is native to much of the U.S. east of the Rocky Mountains, except for New England.

I’ve seen these flowers thriving in several plantings near bike trails or parking lots. I took all of the pictures enclosed below in the main parking area at Brown’s Woods in West Des Moines.

Today’s featured wildflower is easy to cultivate in gardens and has a “rather long” blooming period for a plant that flowers in the early summer. Foxglove beardtongue (Penstemon digitalis), also known as smooth white beardtongue or foxglove penstemon, is native to most of the U.S. east of the Rocky Mountains. Its large flowers (usually white, sometimes shades of pink or lavender) attract a wide range of pollinators.

I was born and raised in Iowa, but moved away at 18 without having learned much of anything about the natural history of Iowa, the history of Euroamerican settler colonialism in Iowa, the history and modern day presence of Indigenous/Native communities in Iowa, many members of whom are among the most passionate protectors of Iowa’s natural resources. Remember, for example, the Meskwaki Nation’s early leadership fighting the portion of the Dakota Access Pipeline running through Iowa, long before broad public attention was drawn to the project.

While hiking this spring I noticed that many parks and preserves are named for or include plaques honoring the mostly white landowners who either sold or gifted the land to the public or the trust, but most feature no education about who was here before that. The Johnson County Conservation board has recently expressed willingness to initiate a project to support learning and unlearning around Iowa history at the sites they manage and on their website, which I hope will center Indigenous voices.

Many of the southeast Iowa sites pictured below are located on lands held by the Meskwaki and Sauk Nations at the time of Euroamerican colonial settlement, as is my own home. One very small way to initiate some learning might be to cross-reference your own map with this one, created by the Historic Indian Location Database project, when visiting Iowa parks and preserves.

Some gorgeous wildflowers bloom in the late spring in Iowa. In prairie habitats you may see spiderwort, prairie ragwort, yarrow, or prairie phlox blooming now. If you’re out and about in a wooded area, you may find Virginia waterleaf, wild geranium, and sweet William.

You may hardly notice today’s featured plant, unless it sticks to your shoes and clothes.

Here we are in late spring. Seeing the prairie flowers begin their parade of blooms this year has been providing me with much needed mental respite from the travails of enduring the fallout of the coronavirus pandemic.  The resilience of spring flowers in the face of an ever-changing environment, and their interdependence with pollinators offer good reminders of what we should aspire to in ourselves.

Speaking of interdependence, last year I posted an essay describing the lifestyle of a late-summer blooming hemiparasitic plant found on my Loess Hills prairie called Slenderleaf false foxglove (Agalinis tenuifolia).

This year, I thought I would use my first Wildflower Wednesday post to describe another curious hemiparasitic plant living on my prairie, the almost ghostly pale-green Downy Yellow Painted Cup (Castilleja sessiliflora). Its other common names include yellow Indian paintbrush or downy paintbrush.

Today’s featured Iowa native is a woody shrub rather than a wildflower, and it’s far from the most beautiful plant blooming on my block right now. But Fragrant sumac (Rhus aromatica) is a hardy plant and good option to consider for landscaping, especially if you need something deer won’t destroy. We had these bushes planted some years ago to replace non-native shrubs (if I recall correctly, they were the highly invasive honeysuckle). They’ve survived tough winters, and the deer we see frequently in this corner of Windsor Heights don’t care for the foliage.

Fragrant sumac is native to almost all of North America east of the Rocky Mountains. According to the Illinois Wildflowers site, it thrives in “full or partial sun, dry conditions, and soil that is sandy or rocky. However, this shrub will adapt to mesic conditions with fertile loamy soil if there is not too much competition from other species of plants.” Small bees or flies will visit the flowers.

If you venture into wet wooded areas in the springtime, there’s a good chance you’ll find some bright yellow flowers. Buttercups can be difficult to distinguish from one another, and multiple sub-species are commonly known as swamp buttercup. I believe the pictures enclosed below are Ranunculus hispidus (hispid buttercup or bristly buttercup).

Some sources refer to a closely related plant as Ranunculus septentrionalis (swamp buttercup), while other sources no longer distinguish between Ranunculus septentrionalis and Ranunculus hispidus. Both species are native to most of the U.S. and Canada east of the Rocky Mountains.

The Illinois Wildflowers website says of swamp buttercup,

This species often grows in soggy areas of woodlands that are too wet for some invasive species, such as Alliaria petiolata (Garlic Mustard). Therefore, populations of Swamp Buttercup remain reasonably secure. This plant is also able to tolerate some degradation of its habitat from other causes.

Incidentally, now would be a good time to pull up garlic mustard if you come across any in nature.

Follow me after the jump for images of swamp buttercup.

It’s been a stressful spring for most of us. But if you can get to a trail or a wooded area–keeping a safe distance from others–you will be treated to a wide variety of native plants blooming now. I’m launching the ninth year of Bleeding Heartland’s wildflowers series (full archive here) with a common woodland plant that is near its peak across much of Iowa: Spring beauty (Claytonia virginica).

Also known as Virginia spring beauty, these plants “will adapt to semi-shaded areas of lawns if mowing is delayed during the spring.” The species is native to most of the U.S. and Canada east of the Rocky Mountains.

Spring beauty has a longer blooming season than some spring wildflowers, like dogtooth violets or Dutchman’s breeches. It can bloom from March through May in Iowa. This year, I didn’t see any flowers until April.

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

Here we are in the deep throes of winter. A wistful melancholy arises from memories of greener and more colorful landscapes, and the dark days and cold dampness of our climate this time of year seems to cage us indoors, leaving us restless with cabin fever.

But the winter landscape has its own serenity, and those adventurous enough to face the chill are often rewarded by sights and sounds unique to the season. 

Last year about this time, I posted an essay here with pictures from a winter snowshoe trek depicting how the new-fallen snow transformed plants on my prairie into more magical, snow-capped versions of themselves.

Before the new political year kicks off with the Iowa legislature convening and Governor Kim Reynolds laying out her agenda, I need to take care of some unfinished business from 2019.

When I reflect on my work at the end of each year, I like to take stock of not only the most popular posts published on this website and the ones I worked hardest on, but also the projects that brought me the most joy. I’ve found this exercise helps guide my editorial decisions on the many days when I have time to write up only one of several newsworthy stories.

Among the 348 posts I wrote last year, these were some of my favorites:

More than 125 authors contributed to the 290 guest posts Bleeding Heartland published this calendar year–way up from the 202 pieces by about 100 writers in 2018 and the 164 posts by 83 writers the year before that. I’m immensely grateful for all the hard work that went into these articles and commentaries and have linked to them all below.

You will find scoops grounded in original research, such as John Morrissey’s exclusive reporting on Sedgwick landing a lucrative contract to administer Iowa’s worker’s compensation program for state employee, despite not submitting the high bid.

The most-viewed Bleeding Heartland post this year was Gwen Hope’s exclusive about the the Hy-Vee PAC donating $25,000 to the Iowa GOP, shortly before President Donald Trump headlined a Republican fundraiser at Hy-Vee’s event center in West Des Moines.

Several commentaries about major news events or political trends were also among the most widely read Bleeding Heartland posts of 2019. I’ve noted below pieces by Ed Fallon, Tim Nelson, Bruce Lear, Randy Richardson, J.D. Scholten, Dan Guild, State Senator Claire Celsi, and others that were especially popular. (This site has run more than 630 pieces since January 1.)

I had planned this post as a reminder of warmer weather, which I assumed we’d all need in late December. But feels like spring today in central Iowa, with temperatures in the high 50s.

Whether you celebrate Chanukah, Christmas, Kwanzaa, winter solstice, or some other holiday this time of year, my gift to you today is one picture from each of the 31 editions of Iowa wildflower Wednesday published during 2019.

I’m grateful to all who helped me with this project, including those who authored posts (Katie Byerly, Lora Conrad, Patrick Swanson) and those who contributed photographs for one of more of my pieces (in addition to the guest authors: Kim El-Baroudi, Jessica Bolser, Rick Hollis, Andy Kellner, Wendie Schneider, Lorene Shepherd, Don Weiss, and David Wehde).

Iowa wildflower Wednesday will return sometime during the spring of 2020. Please reach out if you have photographs to share, especially of native plants I haven’t featured yet. The full archive of more than 200 posts is available here, alphabetized by the plant’s common name.

I was walking a narrow, heavily canopied trail at the Lime Creek Nature Center in Mason City when I first noticed Common blue wood aster (Symphyotrichum cordifolium).

I’ve wanted to write about Sawtooth sunflower (Helianthus grosseserratus) since the earliest months of Bleeding Heartland’s wildflowers series in 2012. Large colonies thrive at the Neal Smith National Wildlife Refuge near Prairie City. But for one reason or another, I’ve never managed to catch them at the height of their blooming period.

After I visited the refuge in early August, I was determined to get back there a few weeks later to capture the sawtooth sunflowers. Again, life got in the way, and I feared these prairie plants had eluded me again.

The first weekend in October, I called the refuge and spoke with a volunteer, who assured me that some sawtooth sunflowers were still blooming near the main parking lot. I took most of the pictures enclosed below there or near the Highway 163 ramp that leads to the refuge (exit 18).

Snow and freezing temperatures arrived early in Iowa this year, but I’m not ready to put Bleeding Heartland’s wildflower series to bed for the winter yet.

The bitter cold inspired me to pull out some summertime pictures for this week’s edition. I took all of the photographs enclosed below in the parking lot of the Greater Des Moines Botanical Garden in late August. Some wonderful prairie plantings are in front of the main building and along the nearby bike trail.

Tall coreopsis (Coreopsis tripteris), sometimes known as tall tickseed, is native to most of the U.S. and Canada east of the Rocky Mountains. UPDATE: Bleeding Heartland user PrairieFan notes in the comments that “tall coreopsis is native to the southern half of Iowa, but not the northern half.”

It can grow in many types of habitats, from disturbed ground to high-quality prairies. The Missouri Botanical Garden’s website advises that tall coreopsis is easy to grow “in dry to medium moisture, well-drained soil in full sun,” and “Thrives in poor, sandy or rocky soils with good drainage.”

According to Aaron Harpold, assistant director of horticulture for the botanical garden, the plants I photographed were a cultivar, not grown from seed collected in the wild. For any interested gardeners, the specific type is Coreopsis tripteris ‘Flower Tower.’
