Liatris spicata, commonly known as blazing star, is a clump-forming perennial with tall spikes of fluffy, deep purple flowers that bloom from the top down. The grass-like foliage grows in dense tufts, adding texture to borders and meadows. Thriving in full sun, it prefers average to moist, well-drained soil and tolerates summer heat and humidity. This pollinator-friendly plant is ideal for rain gardens and prairie plantings, offering reliable seasonal interest and attracting butterflies and hummingbirds.
