Chocolate Cosmos is a one-of-a-kind, must-have flower that gardeners will literally seek out each summer. Prolific reddish-brown flowers dance above 10 - 12 inch mounds of foliage and are chocolate-scented, attracting both humans and pollinators. We treat this tuberous perennial as an annual here in the Pacific NW although the tubers may be dug up after the foliage dies back in the fall and stored on damp peat moss (like dahlias). Alternatively, grow Chocolate Cosmos in a container planter that can be brought into the garage during the winter, and water sparingly until it can be put back out in the spring. No guarantees on its return, but the effort may be worth it if you really love this unique summer flower.
