Шаблон:Short description Шаблон:Speciesbox
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.[1] The common names are whorled tickseed,[2][3] whorled coreopsis, thread-leaved tickseed, thread leaf coreopsis, and pot-of-gold.
Description
Coreopsis verticillata is an herbaceous perennial that grows Шаблон:Convert tall and about Шаблон:Convert 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 Шаблон:Convert across, and both the disc florets and ray florets are bright yellow. The flowers are produced abundantly in clusters from midsummer to fall.[6]
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.[5]
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.[7] They have a long flowering season and are relatively free from pests and diseases.[7] 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 gained the Royal Horticultural Society's Award of Garden Merit:
- 'Grandiflora' - taller than other cultivars, with slightly larger flowers[10]
- 'Moonbeam' - pale, sulphur-yellow flowers, slightly shorter growth, chosen as the 1992 Perennial Plant of the Year by the Perennial Plant Association.[5] When this cultivar was first introduced to the market, demand outstripped supply in some localities, such was its popularity.[11][12]
- 'Zagreb' - shorter than the species, bright yellow flowers[13][14]
