Product Details
Vibrant, bold blossoms on tall stems make a big statement in the garden. Cosmos put on a big show from midsummer until first fall frost, providing pollen and nectar for bees, hummingbirds, and butterflies. Grows loads of cut flowers for your bouquets. A great choice for wildflower areas, as they are drought tolerant and practically care-free. A 1974 All-America Selections winner.
