Tolerant of summer heat and humidity. May be grown from seed, but is slow to establish.
Noteworthy Characteristics
Liatris spicata, commonly called blazing star, dense blazing star or marsh blazing star, is a tall, upright, clump-forming perennial which is native to moist low grounds, meadows and marsh margins. In Missouri, it has only been found in Oregon County on the Arkansas border (Steyermark). It typically grows 2-4' tall in cultivation, but can reach a height of 6' in some parts of its native habitat. Features terminal spikes (6-12" long) of sessile, rounded, fluffy, deep purple flower heads (each to 3/4" across) appearing atop rigid, erect, leafy flower stalks. One or more stalks arise from a basal tuft of narrow, grass-like, medium green leaves (to 12" long). Stem leaves gradually decrease in size toward the top. Blooms in summer. The flowers are attractive to hummingbirds, butterflies, and other pollinators, and the small seeds are attractive to songbirds.
