Vernacular names
English: Whorled Tickseed
polski: nachyłek okółkowy
Coreopsis verticillata is a North American species of tickseed in the sunflower family. 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.[2] The common names are whorled tickseed,[3][4] whorled coreopsis, thread-leaved tickseed, thread leaf coreopsis, and pot-of-gold.
Description
Coreopsis verticillata is an herbaceous perennial that grows 2–3 ft (1–1 m) tall and about 2 ft (1 m) wide, although as it spreads laterally by rhizomes,[5] this width can be exceeded. The stems are wiry.[6] The flower heads are up to 2 in (51 mm) across, and both the disc florets and ray florets are bright yellow. The flowers are produced abundantly in clusters from midsummer to fall.[7]
Habitat
Coreopsis 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.[6]
Horticultural cultivation
Coreopsis verticillata and its horticultural cultivars are not difficult to grow and hence make good starter plants for beginning gardeners in the U.S.[8] They have a long flowering season and are relatively free from pests and diseases.[8] They attract butterflies and are deer resistant.[8] They can be grown in hanging baskets and containers (where irrigation will be necessary), or as border plants.[9] Carolyn Singer, in "Deer in My Garden", reports that C. verticillata is a good companion plant with other summer-blooming perennials requiring similar conditions.[10] The following notable cultivars have gained the Royal Horticultural Society's Award of Garden Merit:
'Grandiflora' - taller than other cultivars, with slightly larger flowers[11]
'Moonbeam' - pale, sulphur-yellow flowers, slightly shorter growth, chosen as the 1992 Perennial Plant of the Year by the Perennial Plant Association.[6] When this cultivar was first introduced to the market, demand outstripped supply in some localities, such was its popularity.[12][13]
'Zagreb' - shorter than the species, bright yellow flowers[14][15]
