10 Perennials That Bloom the Longest

Blanket Flower

Few perennials can tolerate such extremes of heat and cold as our native blanket flowers which grow in U.S. Department of Agriculture Hardiness Zones 3 to 10. They not only survive but thrive, blooming in sunny landscapes from the earliest days of summer through the last frosty days of autumn. Pollinating bees and butterflies make frequent stops to snack on the pollen of the bicolor red and orange blossoms which blanket the mounded foliage.

Full sun and well-drained soil are necessary to grow and successfully overwinter this exceptionally long-blooming perennial.
