Liatris microcephala


Native to the southeastern United States, Liatris microcephala, is a great accent plant to add biodiversity to a green roof. A compact, clump-forming plant with delicate grass-like foliage, it is great nectar source for pollinators. The rose-purple blooms are excellent for attracting birds, hummingbirds, and butterflies. Like most perennials, this plant will benefit from growing in a deeper soil profile, or, where the green roof media has been mounded. It will need regular water to become established.
