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 plant was declared invasive by the United States Southeast Exotic Pest Plant Council in 1996. The flowers of all Cosmos attract birds and butterflies, including the monarch butterfly. 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.

Woo Jang-choon.

Woo Jang-choon was a Korean-Japanese agricultural scientist and botanist famous for breeding plants. He is credited in scientific literature as "U Nagaharu", where "U" is a Korean reading of his Korean family name (禹) but "Nagaharu" is a Japanese reading of the Chinese characters in his Korean given name (長春). Woo was born and raised in Japan, overcoming poverty and discrimination in Imperial Japan to become a prominent researcher and teacher. When Korea was freed of Japanese rule in 1945, Woo left his family in Japan, and traveled to Korea to lead the country's efforts in botany and agriculture. There is a memorial museum in the port city of Busan where he lived and worked in Korea, honoring his life and accomplishments.
