Deeply colored 3" blooms are beauteous in contrast when paired with white flowers and silver-foliage plants. A Fleuroselect Novelty award winner, this cosmos is a real standout in the garden or a vase, and butterflies love them, too. Blooms start out red-wine colored and turn to dusky rose as they age. Growing cosmos is an easy way to add color to your garden, as they require little attention and are drought tolerant.
