Carthamus laevis [2]

Stokesia is a monotypic genus of flowering plants in the daisy family, Asteraceae, containing the single species Stokesia laevis. Common names include Stokes' aster and stokesia. [3] [1] The species is native to the southeastern United States.

The flowers appear in the summer and are purple, blue, or white in nature. [2] The plant is cultivated as a garden flower. Several cultivars are available, including the cornflower blue 'Klaus Jelitto', 'Colorwheel', which is white, turning purple over time, and 'Blue Danube', which has a blue flower head with a white center. [4] More unusual cultivars include the pink-flowered 'Rosea' and yellow-flowered 'Mary Gregory'. [5]

Like a few other plants (such as some species of Vernonia ), it contains vernolic acid, a vegetable oil with commercial applications. [6]

The genus is named after Jonathan Stokes (1755–1831), English botanist and physician. [2]

<i>Clematis</i> Genus of climbing perennial flowering plants in the buttercup family Ranunculaceae

Clematis is a genus of about 380 species within the buttercup family, Ranunculaceae. Their garden hybrids and cultivars have been popular among gardeners, beginning with Clematis 'Jackmanii', a garden standby since 1862; more cultivars are being produced constantly. They are mainly of Chinese and Japanese origin. Most species are known as clematis in English, while some are also known as traveller's joy, a name invented for the sole British native, C. vitalba, by the herbalist John Gerard; virgin's bower for C. terniflora, C. virginiana, and C. viticella; old man's beard, applied to several with prominent seedheads; leather flower for those with fleshy petals; or vase vine for the North American Clematis viorna.

<i>Ficaria verna</i> Species of flowering plant in the buttercup family (Ranunculaceae)

Ficaria verna, commonly known as lesser celandine or pilewort, is a low-growing, hairless perennial flowering plant in the buttercup family Ranunculaceae native to Europe and Western Asia. It has fleshy dark green, heart-shaped leaves and distinctive flowers with bright yellow, glossy petals. It is now introduced in North America, where it is known by the common name fig buttercup and considered an invasive species. The plant is poisonous if ingested raw and potentially fatal to grazing animals and livestock such as horses, cattle, and sheep. For these reasons, several US states have banned the plant or listed it as a noxious weed. It prefers bare, damp ground and is considered by horticulturalists in the United Kingdom as a persistent garden weed; nevertheless, many specialist plantsmen, nursery owners and discerning gardeners in the UK and Europe collect selected cultivars of the plant, including bronze-leaved and double-flowered ones. Emerging in late winter with flowers appearing late February through May in the UK, its appearance across the landscape is regarded by many as a harbinger of spring.
