Cosmos ‘Brownie’
Cosmos atrosanguineus
Description
This exciting introduction from Thompson & Morgan is the first ever chocolate cosmos available from seed. Dark, ferny foliage reveals petite, rich reddish-cocoa blooms that churn out flowers in the heat of summer and autumn. Petals look like they’ve been trimmed with pinking shears, and children love the scent of the flowers—just like dark chocolate. ‘Brownie’ has long, strong, wiry stems up to 2 ft in length, and looks stunning in both bouquets and containers.
