Sulfur Cosmos sulphureus
Cosmos sulphureus is also known as Sulfur Cosmos and Yellow Cosmos. It is native to Mexico, Central America, and northern South America, and naturalized in other parts of North and South America as well as in Europe, Asia, and Australia.
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 plant height varies from 1-7 feet (30-210 cm). 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, following an initiative pursued by the Korean-Japanese botanist Woo Jang-choon.
This plant was declared invasive by the United States Southeast Exotic Pest Plant Council in 1996.
