Yellow daisy-like flowers bloom May through August, providing nectar for pollinators.

See Details Below


Purple-headed Sneezeweed flowers display dark yellow petals encircling a thick purple-colored central disc. Each petal tip is cut into 3 rounded lobes, offering additional interest. Dark green, lance-shaped, toothed leaves grow in an alternating pattern along the thin stem. Native habitat includes wooded swamps, wet meadows, disturbed fields and pastures. It prefers rich, moist soil. Purple-headed Sneezeweed  will tolerate flooding but will not tolerate dry soils or drought. Don’t let the common name fool you, this flower does not cause “sneezing”. Unlike wind pollinated flowers whose pollen may cause allergies, this plant is insect pollinated. Vegetation can be toxic if ingested inlarge quantities, a characteristic that makes this plant deer resistant. Wildlife Value: Nectar and pollen are valued by a variety of bees, wasps, butterflies, flies and other beneficial insects. Host plant for several butterfly caterpillars. Birds eat the seeds.
