False Sunflower
False sunflower (Heliopsis helianthoides) is a perennial wildflower native to eastern North America, including Wisconsin. Reaching heights of three to six feet, it stands tall in grasslands and along woodland edges, where it thrives in full sun and well-drained soil. Its daisy-like flowers are a standout feature—bright yellow petals encircle a golden-brown, cone-shaped center disk, creating a display that measures two to three inches across.
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.
False sunflower also plays an important ecological role. It attracts a wide range of pollinators, including bees and butterflies, and its seeds provide food for birds later in the season. The plant’s deep roots also help stabilize soil, making it a valuable addition to restoration projects and native plant gardens. (July)
