Dense blazing star (Liatris spicata) is a clump-forming perennial that typically grows 3 to 6 feet tall. The tall spikes of flowers bloom from the top down, are showy and attract pollinators. The foliage is grass-like and grows in clumps. 

This low-maintenance plant prefers average to moist, well-drained soils that range from acidic to neutral in pH. It grows well in full sun to partial shade and also tolerates summer heat and humidity. The plant has corms with shallow fibrous roots and can produce new colonies from its corms, though it most often propagates by seed.

It is very attractive in mass plantings in a pollinator garden, rain garden, perennial border, native plant garden, or a cottage garden.

Its flowers are attractive to butterflies, bees, and other pollinators, and Ruby-throated Hummingbirds. American Goldfinches eat the seeds with relish.
