Prairie Blazing Star (Liatris pychnostachya) blooms in Missouri this week. These purple perennial wildflowers serve an important ecological role in the complex community of Missouri’s tallgrass prairies and offer an eye-catching addition to native wildflower gardens.

Discover nature this week, and keep an eye out for one of Missouri’s showiest native wildflowers blooming along roadsides and in tallgrass prairies.

Prairie blazing star (Liatris pycnostachya) is a purple perennial wildflower. Its tall, unbranched, hairy stalks blossom with spikes of dense purple floret clusters from July to October.

Prairie blazing star grows on glades, prairies, blufftops, savannas, ditches, fencerows, pastures, railroads, and roadsides across the state. Nine species of Liatris grow in Missouri and they often hybridize where they occur in the same area.

Also known as gayfeather or button snakeroot, American Indians and early settlers ate the roots, raw or baked, and used the Liatris species to treat a variety of ailments, including snakebites.

Voles and other herbivorous mammals relish the sweet, thickened rootstocks, while a wide variety of insects visit the flowers, and birds feed on the seeds.

Blazing stars are an important part of the complex community of plants in Missouri’s tallgrass prairie and make an appealing addition to native wildflower gardens.
