The Antiquity Cosmos blooms with a rich and evolving color range, opening in burgundy and maturing to an antique bronzy-salmon. This variety blooms early and is very floriferous. Deadhead through the harvest season to keep the flowers blooming longer.

Once established, water only in very dry periods as Cosmos are heat and drought tolerant.
