Prairie blazing star (Liatris pycnostachya) is a towering, alien looking prairie plant that is native to tall grass prairies in the Midwest. This extremely showy native perennial is long blooming and fantastic for pollinators!
Prairie blazing star gets 2-5 ft tall depending on the amount of water it gets throughout the growing season. In dry areas it tend to be shorter. This plant likes full sun to part sun and will usually bloom from July to September.
Prior to flowering, the slender, filiform leaves are extremely attractive and look like a bunch grass up until flowering. Most Liatris species are attractive year round. When is flower, prairie blazing star produces a tall spike of magenta flowers that can reach 20 inches long! These flowers are a favorite amount butterflies, especially monarchs during their migration south.
Seeds begin to form around a month after flowering in the fall. These seeds are a fan favorite of many song birds like gold finches. One plant can produce thousands of small, dandelion-like seeds that allow this plant to volunteer readily in ideal conditions.
Prairie blazing star is unique in that it produces a corn similar to elephant ears and dahlias. This makes them super easy to propagate and move as well. Corms are also readily available at most bulb suppliers.
Prairie blazingstar is just one member of one of my favorite groups of natives. The genus Liatris contains roughly 40 species and they’re all extremely showy! I urge everyone to look into getting Liatris species native to their area. They’re perfect for borders, prairie gardens, formal landscapes, and even cottage gardens!
I will have prairie blazingstar for sale Saturday at the Alton Farmers' & Artisans' Market from 8am-12pm. See you there!
