Garden cosmos

Description:

Cosmos bipinnatus is considered a half-hardy annual, although plants may reappear via self-sowing for several years. The plant height varies from 0.61–1.22 m. The cultivated varieties appear in shades of pink and purple as well as white. Its foliage is finely cut into threadlike segments. When flowering, the plant can become top heavy. This problem is alleviated when grown in groups, as the bipinnate leaves interlock, and the colony supports itself.

Habitat:

Habitats include fallow or abandoned fields, roadsides, areas along railroads, and waste areas. Habitats with a history of disturbance and relatively open ground are preferred.
