Coreopsis verticillata is an herbaceous perennial that grows 2 to 3 feet tall and about 2 feet wide, although as it spreads laterally by rhizomes[1], this width can be exceeded. The stems are wiry.[2] The flower heads are up to 2 inches across, and both the disc florets and ray florets are bright yellow. The flowers are produced abundantly in clusters from mid-summer to fall.
C. verticillata grows naturally in the eastern United States and can commonly be found in dry, thin woods and open pinelands, prefering sites with full sun exposure. It can tolerate drought, poor soil, heat, and neglect.[2] Its native range includes most of North America east of the Mississippi River.[3]
Coreopsis verticillata and its horticultural cultivars are not difficult to grow and hence make good starter plants for beginners. They have a long flowering season and are relatively free from pests and diseases. They attract butterflies and are deer resistant.[4] They can be grown in hanging baskets and containers (where irrigation will be necessary), and as border plants.[5] Carolyn Singer, in "Deer in My Garden" , reports that C. verticillata is a good companion plant with other summer-blooming perennials requiring similar conditions.[6] Notable cultivars include:
