Anacis verticillata (synonym 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.[3] The common names are whorled tickseed,[4][5] whorled coreopsis, thread-leaved tickseed, thread leaf coreopsis, and pot-of-gold.
Description
[edit]Anacis 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,[6] this width can be exceeded. The stems are wiry.[7] 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.[8]
Habitat
[edit]Anacis 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.[7]
Horticultural cultivation
[edit]Horticultural cultivars of Anacis verticillata are not difficult to grow and hence make good starter plants for beginning gardeners in the U.S.[9] They have a long flowering season and are relatively free from pests and diseases.[9] They attract butterflies and are deer resistant.[9] They can be grown in hanging baskets and containers (where irrigation will be necessary), or as border plants.[10] Carolyn Singer, in "Deer in My Garden", reports that A. verticillata is a good companion plant with other summer-blooming perennials requiring similar conditions.[11] The following notable cultivars have gained the Royal Horticultural Society's Award of Garden Merit:
- 'Grandiflora' - taller than other cultivars, with slightly larger flowers[12]
- 'Moonbeam' - pale, sulphur-yellow flowers, slightly shorter growth, chosen as the 1992 Perennial Plant of the Year by the Perennial Plant Association.[7] When this cultivar was first introduced to the market, demand outstripped supply in some localities, such was its popularity.[13][14]
- 'Zagreb' - shorter than most Anacis or Coreopsis species, blooms with bright yellow flowers[15][16]
