Summary

Liatris spicata is a herbaceous perennial native to eastern and central North America, commonly called blazing star or gayfeather. It forms a grass-like clump with tall, erect spikes of purple flowers that open from the top down, reaching about 2–5 feet in height and blooming mid-summer to autumn. Nectar and pollen attract bees, butterflies, and hummingbirds, and seed heads provide winter interest for birds.

It grows in full sun with moist, well-drained soil and tolerates a range of soils, across USDA zones 3–9. Propagation is by seed sown in pots after cold stratification (30–60 days) or by division in spring; first bloom from seed typically occurs in the second year, while divisions can bloom in year one. Plant corms 12–15 inches apart and 2–4 inches deep; water after planting and then rely on established moisture, with deadheading and cutting back after flowering. It is generally pest- and disease-free when drainage is good, and it is valued for borders, meadows, prairie plantings, wildlife gardens, and as cut flowers.
