(Cosmos sulphureus) A different species than the more common cosmos, Diablo showcases bright scarlet/orange, semi-double blooms atop graceful 4-5’ tall and 2-3' wide plants. Easy to grow and will brighten any corner of your garden. Long-lasting and blooming cut/garden flowers bloom early summer through late fall. Drought tolerant and carefree, we keep returning to these as one of our first and favorite flower varieties. Striking vivid color. Native to Mexico and introduced to English horticulture in the 18th century.
