Cosmos bipinnatus (Asteraceae)
A hardy, erect annual requiring very little moisture once established. A native of Mexico, it can easily adapt to all regions of the United States. The attractive flowers are a mixture of stunning deep crimson, soft pink and pure white. Leaves are deeply dissected, almost thread-like in appearance. Rich, fertile soils tend to produce extremely tall, lanky plants. Requires full sun. Sow in early spring, seedlings are not winter hardy. A real value for the money.
Suggested Use: Roadsides, waste areas, mixtures, floral gardens.
Miscellaneous: blooms quickly. Will need to be replanted each spring for continued success.
