Easily grown in average, medium, well-drained soils in full sun.

Tolerant of summer heat and humidity. May be grown from seed, but is slow to establish.
Blazing star (also commonly called 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. Liatris belongs to the aster family, with each flower head having only fluffy disk flowers (resembling "blazing stars") and no ray flowers. The feathery flower heads of liatris give rise to another common name of gayfeather. See also L. spicata 'Kobold' which is a popular compact cultivar that is less likely to need staking than the species.
No serious insect or disease problems. Taller plants may require staking or other support.
