Blazing star (Liatris spp.) is a popular summer flowering perennial. Also called gayfeather, it belongs in the aster family. This tall, upright, clump-forming perennial is found in moist meadows and at the edge of a marsh. (USDA hardiness zones 3-9). Liatris makes an excellent addition to a rain garden.

Its distinctively reddish-purple flower spikes win over a lot of gardeners. Individual flowers, each only ¾ inches across, comprise the floral head which open from the top down to the base. White blooming forms are also available. Multiple stalks rise from the crown, cloth in narrow, grass-like, medium-green leaves. Stem leaves are long and gradually decrease in size near the top. L. spicata ‘Kobold’ is an outstanding compact cultivar that has become the standard bearer in most gardens.

Blazing star grows 2 to 5 feet tall, depending on the fertility of the garden soil. Space plants 12 to 18 inches apart. Once established, plants require very little care. They thrive in their garden space upwards of 3 years, then should be divided, or replaced with new plants.

Blazing star grows in average well-drained soils in full sun. This prairie species is not tolerant of poor drained soils, particularly soggy soils in winter. It excels in moist, fertile soils. Other Liatris species demonstrate better drought tolerance. It’s tolerant of summer heat and humidity. They can be grown from seed, but some are slow to establish. Kobold may spread from seed in its garden spot.

The brightly colored blooms attract numerous birds, butterflies, and unfortunately rabbits. Deadheading will spur re-bloom within 4-5 weeks. A mid-summer fertilizer is advised. Blazing star suffers from no serious insect or disease problems. Taller plants may require staking or other support; ‘Kobold’ rarely requires staking. Flowers make excellent fresh and dried cutflowers.
