Heartstrings Threadleaf Coreopsis is a tidy perennial native with a mounding habit. The narrow deep green foliage is topped with creamy daisy-like with broad deep maroon centers that bleed out to nearly touch the petal edges and flecks along the veins through summer. Prefers full sun and dry to medium well-drained soil. Drought, humidity, and road salt tolerance. The Designer Threads series has excellent powdery mildew resistance.
Coreopsis verticillata is a host for the Silvery Checkerspot Buckeye butterfly, and attracts several other butterflies with its flowers.
