Cosmos atrosanguineus

A captivating "chocolate cosmos," Cosmos atrosanguineus delights with rich, velvety deep-red to maroon blooms tinged with a hint of brown and a distinctive chocolate‑vanilla fragrance that intensifies on warm, sunny days. This elegant, upright perennial grows from tuberous roots, forming slender stems topped with 1–2 inch flowers that bloom from early summer through fall. Ideal for containers, cutting gardens, and borders, it thrives in full sun and well‑drained, moderately fertile soil, and is fairly drought‑tolerant once established. While winter-hardy only in USDA zones 9‑11, gardeners in cooler regions can lift and overwinter the tubers to enjoy its dramatic flair year after year.
