Blanket Flower

Gaillardia grandiflora

Short-lived perennial that is winter hardy to USDA Zones 3-10. Easily grown in average, medium, well-drained soils in full sun. Prefers moist, organically rich soils that drain well but tolerates some dry soils. Performs poorly in unamended heavy clay Missouri soils, however. Many hybrid cultivars may be grown from seed. For those that can, sow seed directly in the garden after last frost date or start seed indoors 4-6 weeks earlier.
