COSMOS atrosanguineus
Plant Common Name
Chocolate Cosmos
General Description
Native to sunny meadows and open areas of Mexico, this appealing perennial is valued for its long-lasting display of velvety, dark maroon flowers that indeed emit a delicate cocoa scent. Spreading slowly via tuberous roots, it possesses an upright, branching habit and is covered with fresh green, somewhat fern-like foliage. Wiry, burgundy stems support a profusion of lush, chocolate-red flowerheads with slightly darker centers which bloom generously from summer into fall.
Chocolate cosmos prefers full sun and well-drained, reasonably fertile soil. At the colder end of its hardiness range, it benefits from the extra protection of winter mulch. Where not hardy, its roots may be lifted before the first frost and stored in lightly moist peat in a cool but frost-free place, much like dahlia tubers. The flowers are attractive to butterflies, and bloom more freely if plants are deadheaded regularly. Use this unique perennial in mixed beds and borders, or in containers where its deliciously-scented blossoms can be enjoyed up close.
