Threadleaf Coreopsis forms a spreading clump of very delicate, ferny foliage. This selection, part of the Sizzle & Spice™ series, bears loads of starry, vibrant sunset-orange flowers, early summer into the fall. Clipping off faded flowers will encourage buds to form all season. Tolerant of hot, dry sites. Excellent for cutting and mass planting. Great for edging in the sunny border, or planting in mixed containers. Tolerates heat and humidity. Easily divided in early spring. Good drainage is necessary.
