Spherical Blazing Star: A Prairie Gem for Your Garden
If you’re looking for a native wildflower that brings both beauty and ecological value to your garden, meet the spherical blazing star (Liatris spheroidea). This charming perennial might not be the most famous member of the blazing star family, but it’s certainly worth getting to know!
What Makes Spherical Blazing Star Special?
The spherical blazing star gets its name from its distinctive round, globe-like flower clusters that sit atop sturdy stems. Unlike some of its spikier cousins in the Liatris family, this species produces dense, spherical heads of purple-pink flowers that bloom from late summer into early fall. The narrow, grass-like leaves create an attractive backdrop for these eye-catching blooms.
As a native forb (that’s botanical speak for a non-woody flowering plant), spherical blazing star is a perennial that will return year after year, gradually forming lovely clumps in your garden.
Where Does It Call Home?
This prairie native has quite an impressive range across the central United States. You’ll find spherical blazing star naturally growing in Arkansas, Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, Ohio, Tennessee, and Wisconsin. It’s particularly at home in prairie ecosystems where it has evolved alongside native grasses and other wildflowers.
Why Your Garden (and Local Wildlife) Will Love It
There are several compelling reasons to consider adding spherical blazing star to your landscape:
- Pollinator magnet: The nectar-rich flowers are irresistible to butterflies, bees, and other beneficial insects, providing crucial late-season food sources

- Late-season color: Extends your garden’s blooming period into fall when many other flowers are fading
