Cosmos Bipinnatus, generally known as the Cosmos or the “Mexican Aster”, is a medium sized flowering herbaceous plant sometimes grown in gardens.
This species is considered a half-hardy annual, although plants may re-appear via self-sowing for several years. The plant height varies from two to four feet.
The cultivated varieties appear in shades of pink and purple as well as white. Its foliage is finely-cut into threadlike segments.
