Liatris spicata ‘Kobold’, or blazing star is a small, compact, upright, clump-forming perennial which typically grows 24 to 30 inches tall. The popularity of this plant comes from the unusual terminal spikes (6 to 15 inches in length) of sessile, rounded, fluffy, deep purple flower heads (each is about ¾ inches across) appearing atop rigid, erect, leafy flower stalks.

Multiple stalks arise from basal tufts of narrow leaves (about 10 inches in length). Flowers generally open top to bottom on the spikes. The bloom period is July to August. Liatris belongs to the aster family, with each flower head having only fluffy disk flowers (resembling “blazing stars”) and no rays.
