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 threadlike 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.
