Cosmos sulphureus
Cosmos sulphureus is also known as Sulfur Cosmos and Yellow Cosmos. Its native habitat is Central America. This species of Cosmos is considered a half-hardy annual, although plants may re-appear via self-sowing for several years. Its foliage is opposite and pinnately divided. The original and its cultivars appear in shades of yellow, orange, and red. It is especially popular in Korea and Japan, where it is often seen in mass plantings along roadsides.
Plants of yellow cosmos can range in height from 4 to 7 feet but the cultivated varieties such as 'Crest Red', 'Ladybird Dwarf Red', 'Ladybird Dwarf Gold', 'Ladybird Dwarf Orange', 'Ladybird Dwarf Lemon', and Yellow Cosmos - Klondyke Mix are not as tall. The flower heads are composed of disc and ray flowers. The disc or center flowers are yellow: the ray, or outer petals range from pale yellow or mustard to orange-scarlet. Red is a relatively recent addition to the color range of C. sulphureus. The native species is golden-yellow to orange.
