Common Milkweed (Asclepias syriaca)
Common Milkweed is a native, perennial wildflower. It can grow up to five feet tall. It bears cream-colored, pink-tinged flowers, 1/2 inch wide, that form round clusters up to two inches wide. Each flower has five downward-pointing petals and a five-part pointed crown. It has large, toothless leaves that are four to six inches long and bleed a milky sap when torn. Within its range it can be found in a broad array of habitats from croplands to pastures, roadsides, ditches and old fields. It is surprisingly rare in prairies in the Midwest, being found mostly in disturbed sites due to its inability to compete with other vegetation.
In Wisconsin alone, there are twelve native species of milkweed, and while they differ in form and habitat preference, they all play a critical ecological role as host plants for monarch butterfly caterpillars. Monarchs lay their eggs exclusively on milkweed species, and the emerging caterpillars depend entirely on the plant for nourishment. As they consume the leaves, they ingest natural toxins that deter most predators—an elegant defense mechanism passed from plant to insect. This specialized relationship makes every milkweed planting an act of conservation, supporting monarch populations that are increasingly threatened by habitat loss and environmental changes. (July)
Michigan Lily (Lillium michiganense)

The Michigan Lily
Michigan lily (Lillium michiganense) grows two to five feet tall. It is a single-stemmed wildflower with sword-like leaves arranged in whorls. Its stem often branches at the tip to form additional flower stalks. Orange flowers, up to three inches across, have petals that curve backward. Dark spots mark the inner surface of the six petals. It prefers full to partial sun, loamy or sandy soil, and moist conditions.
Though often mistaken for its close relative, the Turk’s cap lily (Lilium superbum), the Michigan lily is native to Wisconsin and the Turk’s cap lily is not; but they can be easily distinguished. The Turk’s cap lily has a green star at the base of its flower that is absent in the Michigan lily. Michigan lily flower buds are slender and often reddish-orange, while Turk’s cap lily buds are plumper and sometimes hint at a green star early on. Also, Michigan lily leaves feel slightly rough, while Turk’s cap lily leaves are smooth to the touch.
Another point of distinction is how these two lilies spread through their native ranges. While Turk’s cap lily often forms larger, denser colonies throughout the Southeast and Eastern United States, the Michigan lily tends to appear in scattered, more solitary patches across the Midwest. (July)
Clasping Milkweed (Asclepias amplexicaulis)
Purple Prairie Clover (Dalea purpurea)
Showy Tick Trefoil (Desmodium canadense)
Showy tick trefoil (Desmodium canadense) is a tall, bushy perennial wildflower native to North America, including Wisconsin. Reaching heights of two to six feet, it produces clusters of pink to purple, pea-shaped flowers near the tops of its slender stems during mid to late summer.
Obedient Plant (Physostegia virginiana)
Hoary Vervain (Verbena Stricta)
Butterfly Milkweed (Asclepias tuberosa)
Swamp Milkweed (Asclepias incarnata)
Swamp Milkweed (Asclepias incarnata)
Swamp milkweed is a native, perennial wildflower in Wisconsin. It typically grows three to five feet tall. The flowers bloom in shades of pink, mauve, or occasionally white. Each individual flower is about 1/4 inch in diameter, but they are arranged in clusters that can be two to three inches in diameter. Lance shaped leaves grow in pairs along the stem. They are three to six inches long and one to two inches wide. This plant prefers moist to wet soils and is often found in wetlands, along streams, and in wet meadows. It thrives in full sun, but it can tolerate partial shade.
Ecologically, it plays a vital role as a host for monarch butterflies, providing both a nursery for caterpillars and a nectar source for adults, while also attracting bees, hummingbirds, and other butterflies. It adapts to garden soils with adequate watering and is hardy across much of the Midwest. In addition to its ornamental use, swamp milkweed resists deer browsing and tolerates heavy clay soil, making it suitable for rain gardens and naturalized borders. It spreads slowly via underground rhizomes and can be propagated by seed—though successful germination typically requires a chilling period to mimic winter dormancy. Historically, its fibers were used for twine and buoyant stuffing, and some Indigenous groups employed it medicinally for respiratory issues. While beautiful and ecologically beneficial, it contains cardiac glycosides that are toxic if ingested in quantity. (July)
False Sunflower (Heliopsis helianthoides)
The foliage of false sunflower is equally distinctive. Its ovate leaves grow in opposite pairs along the stem and can reach up to six inches in length. The leaf margins are toothed, and the surface has a rough, sandpapery texture that helps deter browsing animals like deer and rabbits. These sturdy stems and coarse leaves support a long blooming season, typically stretching from early summer into fall.
Tall Bellflower (Campanula Americana)
Wild Germander (Teucrium canadense)
This plant belongs to the mint family and is widespread across much of North America. Its square stems and opposite leaves are typical of mint relatives, and its flowers bloom from June to September. Each flower has a broad lower lip that serves as a landing pad for pollinators such as bees, butterflies, and flies. The upper lip is nearly absent, but four long stamens arch outward through a slit, giving the flower a distinctive appearance that resembles an orchid when viewed head-on.
Wild germander spreads through rhizomes, forming colonies in suitable habitats. Its root system is fibrous, and the plant can tolerate a range of soil types, though it prefers moist to medium-moist conditions. It is hardy in USDA zones 4 through 9 and can grow in full sun or partial shade. While the flowers are visually striking, they lack fragrance. After blooming, each flower produces four small seeds enclosed in a persistent calyx.
Historically, Native Americans used wild germander for medicinal purposes. The leaves were steeped in water to treat skin sores and ulcers, and teas were made for various ailments. However, modern herbal use has declined due to concerns about liver toxicity associated with certain compounds found in the plant. Despite this, it remains an important species for pollinators and is often included in native plant gardens and restoration projects.
