Harebell (Campanula rotundifolia)

Sometimes mistaken for creeping bellflower, harebell is a native perennial wildflower found in Wisconsin and across much of North America. It thrives in a variety of open or lightly shaded environments, including rocky outcroppings along rivers, meadows, and prairies. It prefers well-drained soils. Despite its fragile appearance, harebell is well-adapted to dry, sandy, and gravelly soils, making it a common sight in rugged landscapes. It is resistant to deer and drought. Its long blooming period, from late spring to early autumn, ensures a continuous display of delicate flowers throughout the growing season.

It grows up to 20 inches tall, with thin, wiry stems that support its nodding, bell-shaped flowers. Each flower is less than an inch long and consists of five fused petals, forming a soft, pale bloom. The basal leaves, withering by flowering time, are round, measuring between half an inch to one inch wide, while the upper leaves are grass-like, reaching about three inches in length and only 1/8 to 1/4 inch wide. These leaves alternate along the stem, contributing to the plant’s airy and delicate structure.

Harebell’s historical and cultural significance adds to its charm. In folklore, it has been associated with fairies and enchantment, earning names such as "witch’s thimble" and "bluebell of Scotland." Despite its whimsical reputation, it remains a tough and adaptable plant, capable of thriving in challenging conditions.

Purplestem Angelica (Angelica atropururea)

Purple-stemmed Angelica is a perennial native to eastern and central North America—including Wisconsin. It can grow up to ten feet tall with most plants in the four to eight foot range. Its flowers are small, only about a quarter inch across, but they bloom in large umbrella-like clusters called umbels that span 8 to 10 inches wide. The flowers are typically white to greenish-white and bloom from late spring into summer. The leaves are compound and can reach up to 24 inches in both length and width. Each leaflet grows to about 4.5 inches long and 2.5 inches wide, with a toothed, oval to lance-oval shape. The stems are hollow, smooth, and purple. They are typically 1 to 2 inches thick. Purple-stemmed Angelica prefers moist to wet, nutrient‑rich soils, with a slightly acidic to neutral pH. It thrives in sunny marshes, wet meadows, and along streambanks, especially where the soil has some lime content, but can survive in partial shade.

Ecologically, purple angelica—as a member of the carrot family—plays a valuable role in supporting biodiversity. Like many other Apiaceae species, it features umbels of flowers that are especially attractive to a wide range of pollinators, including bees and flies. While specific larval host associations for purple angelica remain under-documented, related species in the family are known to support caterpillars of butterflies and moths. By offering nectar, pollen, and shelter, purple angelica contributes to the ecological richness of the wetland environments where it thrives.

Cow Parsnip (Heracleum maximum)

Cow parsnip (Heracleum maximum) is a tall, native wildflower found across North America, including Wisconsin. It typically grows 4 to 10 feet tall and bears broad, flat‑topped compound umbels of small white flowers, each umbel spanning 4 to 12 inches across. Individual flowers are about a quarter inch wide, with larger, showier blossoms often forming a lacy ring around the edge. The leaves are enormous and divided into three large lobes or leaflets, with basal leaves reaching up to 18 inches long and wide; their surfaces are softly hairy and coarsely toothed. The stem is thick, hollow, ridged, and covered in fine white hairs, sometimes approaching 2 inches in diameter. Cow parsnip thrives in full sun to partial shade in moist, nutrient‑rich soils, especially along streambanks, forest edges, wet meadows, and cool alluvial flats. Its sap contains furanocoumarins that can cause skin irritation when exposed to sunlight, making it a plant best admired without handling. Ecologically, cow parsnip is an important summer nectar source, supporting a wide range of pollinators—including bees, flies, beetles, and butterflies—drawn to its abundant, accessible umbels.

Sessile-leaf Bellwort (Uvularia sessilifolia)

Sessile‑leaf bellwort carries a little woodland intrigue: after it blooms, the plant relies on ants to disperse its seeds, each tipped with a tiny food reward that lures the insects into carrying them deeper into the forest. This delicate spring wildflower grows 4 to 12 inches tall and produces a single drooping, pale yellow flower about an inch long, with six slender, slightly curved tepals. Its leaves—up to 3 inches long and an inch wide—attach directly to the stem without stalks, and the upper stem forks into a subtle zig‑zag pattern that helps position the blossom in the dim understory light. The upper stem often shows a faint reddish‑purple tint as it matures. Blooming early in the season, it offers nectar to the first solitary bees of spring, a valuable resource when few other flowers are open. Sessile‑leaf bellwort thrives in shaded to partly shaded forests with moist, well‑drained, humus‑rich soils and spreads by slender underground stolons, forming loose colonies in long‑undisturbed woodland habitats.

Seneca Snakeroot (Polygala senega)

Seneca snakeroot is a perennial herb typically 10 to 18 inches tall. Its flowers form dense, spike‑like racemes at the stem tip, with each small bloom about 1/6 inch long and colored white to greenish‑white, ending in a distinctive fringed crest. The leaves are 1 to 3 inches long and 1/3 to 1 1/3 inch wide, linear to lance‑elliptic, widest at or just below the midpoint, and either smooth or minutely hairy.

This species grows in full to partial sun and favors dry to mesic, well‑drained soils—especially sandy, gravelly, or rocky substrates. In Wisconsin it is found in prairies, savannas, open woodlands, and dry, rocky stream margins or slopes. Its presence often signals intact, undisturbed native plant communities.

Spiranthes lucida, commonly known as shining lady’s tresses, is a perennial orchid native to northeastern North America, including Wisconsin where it reaches the western edge of its range. It typically grows up to 15 inches tall and produces white flowers in a spiral arrangement along a single spike, each featuring a yellow lip. The basal leaves are lance-oblong and remain during flowering.

The species blooms from late May and fruits by mid-Summer. It inhabits saturated but not flooded, calcareous soils in places such as streambanks, fens, river terraces, and old quarries. Its range extends from Nova Scotia to northeastern Wisconsin, and south to Virginia, Arkansas, and Missouri.

Pollination is primarily carried out by short-tongued bees, particularly from the Halictidae family. In some regions, including Wisconsin, it is listed as a species of special concern due to habitat sensitivity.

Wood Nettle (Laportea canadensis)

Unloved but Essential: Embracing Unpopular Plants for Biodiversity

From the shaded understory of Wisconsin’s mesic forests emerges Laportea canadensis, or wood nettle—a plant more likely to provoke a sting than admiration. Yet beneath its defensive hairs lies a species that plays an important role in healthy forest systems: shaping microhabitats, supporting invertebrate life, and helping maintain soil stability in moisture‑rich environments.

In landscaping, a plant’s value is often measured by showiness or ease of control. But native species like wood nettle—frequently dismissed as weeds—provide functional ecological services that ornamental plants rarely match. Their presence contributes to layered forest structure, supports specialist insects, and helps buffer ecosystems against disturbance.

Wood nettle thrives in moist, nutrient‑rich soils of floodplains, stream terraces, and low hardwood stands across Wisconsin. It typically reaches two to four feet in height, with broad, alternate leaves up to six inches long. The serrated margins and stinging trichomes deter herbivory, while its separate male and female flowers—small, greenish, and wind‑pollinated—allow the plant to reproduce efficiently in shaded conditions. Dense colonies help slow surface runoff, modestly reduce erosion, and create cool, humid microclimates used by ground beetles, spiders, amphibians, and the larvae of several native moths.

Plants like this are easy to overlook—too plain, too wild, too defensive for garden culture. But wood nettle illustrates a larger ecological truth: biodiversity depends on functional diversity, not just floral charisma. Understory species that seem unremarkable to us often support entire guilds of organisms that more celebrated plants cannot.

Rethinking our private landscapes—through approaches such as meadow‑scaping or simply reducing the dominance of turf—allows us to welcome complexity back into the places we steward. Incorporating native species, including the less glamorous ones, transforms simplified yards into living habitat. And while wood nettle itself is best left to the moist forest soils where it belongs, learning to value plants like it helps shift our attention from aesthetics alone to the ecological work that sustains the land.

Annual Fleabane (Erigeron annus)

Annual fleabane (Erigeron annuus) is a native Wisconsin wildflower common in disturbed places such as pastures, old fields, roadsides, and railways. It typically grows one to three feet tall, occasionally taller in rich soils. By late spring it produces loose clusters of small aster-like flower heads: a bright yellow center of tubular disk florets surrounded by 50 to 100 narrow rays that range from white to pale lavender. Each flower head measures about one-half to three-quarters of an inch across, creating the plant’s soft, airy appearance.

The leaves are alternate and sessile, attaching directly to the stem. Lower leaves are broader and often toothed, while the upper leaves become narrower and mostly untoothed. The stems are green and sparsely hairy, giving the plant a slightly rough texture.

As a pioneer species, annual fleabane readily colonizes disturbed soils, helping to stabilize loose ground and provide early nectar and pollen for small bees, syrphid flies, and tiny wasps. It plays a useful early role in restoration sites, though it is not a strong competitor against aggressive invasive plants.

Foxglove Beardtongue (Penstemon digitalis)

Foxglove beardtongue (Penstemon digitalis) is a hardy perennial wildflower native to eastern North America and widely naturalized across Wisconsin. Bonap recognizes it as adventive in Wisconsin, but native in lower and upper Michigan, Illinois, and Iowa. Growing three to five feet tall, it produces loose clusters of white to pale pink, tubular, two‑lipped flowers that resemble small foxgloves. These blossoms are especially important to early‑season pollinators: bumble bees, small native bees, and miner bees use the tubular flowers efficiently, while hummingbirds and butterflies visit opportunistically. The plant’s opposite, lance‑shaped leaves line the stem, with a basal rosette forming in spring.

Ecologically, foxglove beardtongue contributes nectar during a seasonal gap when few other prairie plants are blooming, supports specialist bee species, and provides structure and cover within open habitats. It thrives in prairies, meadows, woodland edges, fields, and disturbed areas such as roadsides and powerline corridors, preferring full sun to partial shade and well‑drained soils.

Carolina Rose (Rosa carolina)

Rosa carolina, commonly called Carolina rose or pasture rose, is a low, deciduous shrub that typically grows 1 to 3 feet tall, though it may reach greater heights in rich soils. It spreads 1 to 5 feet wide and often expands by suckers, forming loose thickets. The plant bears fragrant pink flowers—usually solitary, sometimes in pairs or threes—measuring 2½ to 3 inches across. Its upright stems carry straight, needle‑like prickles, and the smooth, dark green compound leaves turn yellow to red in fall. Carolina rose thrives in a wide range of habitats, including dry prairies, open woods, savannas, streambanks, and roadsides, and it tolerates heat and periodic drought once established.

Ecologically, its thickets provide nesting and escape cover for birds and small mammals, while the summer blooms supply nectar and pollen for native bees. The bright red hips that form in late summer persist into winter, offering an important cold‑season food source for wildlife.

Ohio Spiderwort (Tradescantia ohiensis)

Ohio spiderwort earns its ecological value by supporting pollinators during a seasonal lull, when spring ephemerals are fading and summer prairie flowers haven’t yet taken over. In Wisconsin, it begins blooming in late May, offering nectar and pollen just as bumblebees, sweat bees, and other early‑summer pollinators are ramping up. Because the plant produces new buds continuously, fresh flowers across several weeks, creating a steady, reliable resource during this transition period.

A native perennial, Ohio spiderwort grows one to three feet tall on upright, unbranched stems. Its three‑petaled flowers range from blue to violet, with occasional pink or nearly white forms, and each bloom carries six hairy, yellow‑tipped stamens that give the flower its distinctive texture. The blossoms appear in terminal clusters of up to 20, each cluster subtended by long, slender, leaf‑like bracts.

The plant’s grass‑like leaves form a basal clump, each leaf 8–16 inches long and typically less than an inch wide, arching as the season progresses. Ohio spiderwort grows best in sunny, moist, well‑drained soils, but it is notably adaptable, tolerating partial shade, drier conditions, and a range of soil types once established.

Indian paintbrush (Castilleja coccinea)

Indian paintbrush is a striking native wildflower found in Wisconsin and across much of the eastern and central United States. This biennial plant reaches a height of one to two feet, standing tall with its distinctively hairy single stem.

Its flowers, though greenish yellow and only about an inch long, are the main attraction. What catches the eye are the vivid red-tipped bracts—specialized leaf-like structures—that cluster together, creating the illusion of a brilliant bloom. These three-lobed bracts contrast beautifully with the plant’s alternate, deeply-lobed leaves.

Indian paintbrush thrives in moist environments, often appearing in open fields, prairies, and rocky outcroppings. Interestingly, it's a hemiparasitic plant, meaning it taps into the roots of nearby grasses and other plants for nutrients while still producing its own food through photosynthesis.

Bunchberry Dogwood (Cornus canadensis)

Photo by Jan Tezlaff

Bunchberry dogwood (Cornus canadensis) is a low‑growing perennial native to northern North America, including Wisconsin, as well as much of Canada and parts of the northeastern United States. This plant thrives in cool, damp, and shady woodlands, often found beneath towering trees and shrubs.

Typically reaching just six to nine inches in height, bunchberry dogwood forms a dense, ground‑covering mat that plays an important role in forest function. Its creeping rhizomes help stabilize the thin, organic soil layer on the forest floor, slowing erosion and holding moisture where seedlings, mosses, and fungi depend on it. The plant’s low canopy shades the soil, reducing evaporation and maintaining the cool microclimate characteristic of northern hardwood and conifer forests. In late spring, its tiny true flowers—surrounded by four white bracts—provide nectar and pollen for small native bees and flies. By late summer, the bright red berries offer food for thrushes, grouse, chipmunks, and other wildlife, adding diversity to the seasonal diet of forest animals.

A key characteristic of bunchberry dogwood is its veining—unlike many plants, its veins curve outward toward the leaf tip. The short‑stalked leaves measure around three inches long and two inches wide, with a distinct wedge‑shaped base and abruptly pointed tips.

Large-flowered Beardtongue (Penstemon grandiflorus)

When you find Large‑flowered Beardtongue, you’re standing in a remnant — a fragment of the original prairie lands that once were common across Wisconsin. You don’t stumble on this plant. It grows where the land still resembles what it was before the plow: the dry, sandy prairies and gravelly ridges that escaped cultivation by luck or by the stubbornness of their soil. In those places, you can still find beardtongue, its blue‑gray leaves thickened against drought and its tall stem lifting oversized lavender‑pink flowers into the open air. It’s a species that marks a certain kind of ground, the kind that has held onto its wildness just long enough for a few prairie specialists to persist.

The plant rises as a single stem reaching one to three feet, topped with oversized lavender‑pink tube-shaped blossoms. The flowers jut outward from the upright raceme like small trumpets, each nearly two inches long, built for the heavy buzz of bumble bees. Smaller bees crawl inside but rarely do the job — the plant has evolved for the heft and reach of the big pollinators that once worked the prairies in abundance.

Large-flowered beardtongue is a plant shaped by drought and open sky. The first thing you notice, even before the flowers, is the foliage. The leaves are blue‑gray, thick, and faintly waxy, with the succulent look of a plant that expects long stretches without rain. In its first year, the plant stays low, forming a rosette with leaves that can reach six inches long. Only in the second year does it send up the flowering stalk — a two‑stage life cycle that mirrors the rhythms of many prairie perennials.

Everything about the plant is an adaptation to scarcity: the water‑holding leaves, the smooth, unbroken margins that reduce transpiration, the deep taproot that drills into sand and gravel for moisture. It’s a species that thrives where others falter, using the very harshness of the site as its competitive edge.

Like many dry‑prairie plants, Large‑flowered Beardtongue responds well to periodic fire. Flames clear away the grasses and young shrubs that would otherwise shade it out. After a burn, the soil warms quickly, and the beardtongue often responds with stronger flowering. In this way, the plant is tied not just to a habitat, but to a process — a reminder that prairie is not a place so much as a cycle of disturbance and renewal.

Watch the plant for a few minutes in June and you’ll see its purpose. Bumble bees land heavily on the inflated corolla, pushing inside to reach the nectar. As they back out, pollen dusts their bodies in just the right places to touch the next flower’s receptive surface. It’s a simple exchange, but it’s been refined over thousands of years: a flower built for a bee, and a bee built for a flower.

This is the kind of detail that turns a field observation into a story — a glimpse of the old prairie economy still functioning in miniature.

Finding Penstemon grandiflorus in Wisconsin is like finding a geological clue. It marks sandy outwash, dry ridges, old glacial deposits, and prairie edges that resisted farming. It’s a species that reveals the land’s history as much as its present.

Star Flower (Trientalis borealis)

Starflower's white, seven‑pointed blooms hover just above the leaf litter, small but unmistakably bright against the dim understory. A native perennial across Wisconsin and the northern forests of the United States, Trientalis borealis thrives where the soil runs acidic and the light filters softly through conifers and hardwoods.

Growing four to eight inches tall, starflower is modest in stature but elegant in form. One or two star‑shaped blossoms rise on slender stalks above a whorl of five to seven lance‑shaped leaves. Each flower is about half an inch wide, its sharply pointed petals giving it the symmetry that makes the plant so distinctive.

Starflower’s blooms offer nectar to native bees and other small pollinators that work the forest floor in spring and early summer. The plant spreads by thin, creeping rhizomes, forming loose colonies that help it persist in the shifting conditions of moist to dry, acidic woodland soils. Where it grows well, starflower contributes to the layered structure of healthy northern forests — one of the many small species that, together, sustain the diversity and resilience of these ecosystems.

White Wild Indigo (Baptisia alba)

Rising three to four feet above the prairie, white wild indigo flower spikes stand like small beacons in early summer, bright against the greens and golds of Wisconsin’s open landscapes. A native perennial found throughout the central and eastern United States, Baptisia alba is a tough, long‑lived plant built for the extremes of Midwestern weather.

Its tall, erect stems hold long racemes of pea‑shaped blossoms, each about an inch long and reminiscent of lupine. When the flowers open, they draw in bees, butterflies, and other pollinators, adding motion and sound to prairies, open woodlands, and roadsides.

The foliage is just as distinctive. Bluish‑green compound leaves, divided into three leaflets two to four inches long, give the plant a clean, architectural look. This trifoliate structure, paired with a deep, resilient root system, helps the plant withstand drought, poor soils, and the pressures of full sun. Once established, white wild indigo shrugs off deer, disease, and long dry spells, making it a reliable choice for restorations, erosion control, and tough roadside plantings.

As a legume, it fixes nitrogen and enriches the soil around it. Its flowers feed a wide range of pollinators, and its foliage supports the larvae of the wild indigo duskywing butterfly. In a healthy prairie, Baptisia alba is both a visual anchor and a driving force for biodiversity.

Canada Mayflower (Maianthemum canadense)

Canada mayflower (Maianthemum canadense) is a delicate, native perennial wildflower found throughout Wisconsin and much of the northeastern United States. This small woodland plant grows three to six inches tall and thrives in cool, shaded forests, especially in moist, mossy areas beneath conifers or mixed hardwoods. Its preference for shade to part shade makes it a characteristic species of rich northern woods.

In spring, Canada mayflower produces a short, upright cluster of tiny, star‑shaped white flowers. Each bloom has four tepals and four stamens, giving the cluster a fine, airy appearance. The plant typically bears one or two leaves, occasionally three, which are oval to heart‑shaped, smooth‑edged, and one to three inches long. These leaves arise near the base of the stem rather than alternating along it.

Canada mayflower spreads vigorously by underground rhizomes, forming dense carpets that help stabilize forest soils and suppress erosion. By midsummer, the flowers give way to small berries that ripen from green to mottled red with pale speckles. These fruits are eaten by a variety of wildlife, including birds, chipmunks, mice, and ruffed grouse.

In garden settings, Canada mayflower is a valuable native groundcover for shaded areas. It adapts well to acidic, humus‑rich soils and can tolerate both moist and moderately dry conditions once established. Its ability to form lush, low‑growing colonies makes it an appealing choice for naturalistic plantings and for gardeners seeking to enhance biodiversity with dependable woodland species.

Gaywings (Polygaloides paucifolia)

Photo by Judith Kozminski

Gaywings, also known as fringed polygala, is a small, spring‑blooming wildflower native to Wisconsin and much of the northeastern United States. This perennial grows in acidic, humus‑rich conifer or mixed forests, often beneath pines or hemlocks, where it thrives in part shade to full shade. Plants typically reach three to seven inches tall, forming low patches on the forest floor.

Each plant produces one to four blossoms, deep pink to nearly white, each less than an inch wide. The flowers are unmistakable: two large, wing‑like sepals flare outward like tiny propellers, while the lower petal forms a fringed keel that gives the species its common name. The leaves cluster toward the tip of the stem, elliptic, smooth‑edged, and sometimes fringed with minute hairs.

Blooming in spring to early summer, gaywings add a vivid splash of color to shaded woodlands. Their ecological role extends beyond pollination by small bees. Like many spring wildflowers, they rely on ants for seed dispersal, a strategy known as myrmecochory. The seeds bear elaiosomes, nutrient‑rich attachments that attract ants. Ants carry the seeds back to their nests, consume the elaiosomes, and leave the seeds to germinate underground. This process helps spread the plant across the forest floor and supports genetic diversity within populations.

Smooth Sweet Cicely (Osmorhiza longistylis)

Smooth Sweet Cicely (Osmorhiza glabrata)

Smooth sweet cicely is a native perennial of Wisconsin’s rich woodlands, typically growing one to three feet tall. In late spring, it produces delicate clusters of tiny white flowers, each only about 1/16 to 1/8 inch wide, arranged in small, open umbels at the tips of stems and branches. Like other members of the carrot family, each flower has five white petals, five stamens, and two slender styles that extend slightly beyond the petals.

Its foliage is one of its most distinctive features. The leaves are compound, fern‑like, and finely divided, usually three to six inches long. Each leaf is split into three main sections, and each section is further subdivided into smaller leaflets, giving the plant a soft, lacy appearance on the forest floor.

Smooth sweet cicely grows in moist, well‑drained soils of shaded to partially shaded woods, ravines, and slopes. It favors the humus‑rich, slightly acidic to neutral soils typical of mature forests. The plant is an important nectar source for a wide range of small pollinators, including bees, flies, wasps, and moths, all of which are drawn to the accessible flowers of umbellifers.

Reproduction occurs primarily through seed, which ripens in elongated, aromatic fruits typical of the genus. Seeds require a period of cold stratification to germinate, often sprouting the following spring. Unlike garden perennials, smooth sweet cicely is not typically propagated by division or cuttings; its roots are delicate, and the plant prefers to establish naturally from seed within stable woodland soils.

A long‑lived species, smooth sweet cicely persists quietly in the understory, contributing to the structure and diversity of Wisconsin’s forest communities. When brushed or crushed, its foliage releases a subtle anise‑like fragrance, a reminder of its place among the aromatic members of the carrot family.
