It is found primarily in the east-central United States, from Maryland south to Georgia, with isolated populations as far west as Oklahoma and as far north as Québec and Ontario.[1] The common names are whorled tickseed,[2][3] whorled coreopsis, thread-leaved tickseed, thread leaf coreopsis, and pot-of-gold. DescriptionCoreopsis verticillata is an herbaceous perennial that grows {{convert|2|-|3|ft|0|abbr=on}} tall and about {{convert|2|ft|0|abbr=on}} wide, although as it spreads laterally by rhizomes,[4] this width can be exceeded. The stems are wiry.[5] The flower heads are up to {{convert|2|in|0|abbr=on}} across, and both the disc florets and ray florets are bright yellow. The flowers are produced abundantly in clusters from midsummer to fall.[6]HabitatCoreopsis verticillata can commonly be found in dry, thin woods and open pinelands, preferring sites with full sun exposure. It can tolerate drought, poor soil, extreme heat, and neglect.[5]Horticultural cultivationCoreopsis 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.[7] They can be grown in hanging baskets and containers (where irrigation will be necessary), or as border plants.[8] Carolyn Singer, in "Deer in My Garden", reports that C. verticillata is a good companion plant with other summer-blooming perennials requiring similar conditions.[9] The following notable cultivars have all gained the Royal Horticultural Society's Award of Garden Merit:-
