10 Cosmos bipinnatus Seeds - Sea Shells Cosmos - Sow Spring Summer - Annual

Cosmos bipinnatus, commonly called the garden cosmos or 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. When flowering, the plant can become top heavy. This problem is alleviated when grown in groups, as the bi-pinnate leaves interlock, and the colony supports itself. The plant is easy to grow with no special soil treatment. It prefers good soil, but will adapt to almost any environment except a constantly wet one. Ferny seedlings are easy to transplant. Excellent Cut Flowers!
