It’s hard to beat sulfur cosmos (also known as orange cosmos) for brightly colored blooms! The loosely branched plants produce an abundance of clear orange flowers from midsummer to frost. Unlike other, compact strains of Cosmos sulphureus, these seeds consistently produce 4- to 6-foot-tall plants in my garden. They’re terrific as fillers in young perennial or mixed borders, or as a tall annual screen planting. They’re perfectly in scale with other tall annuals, such as ‘Hopi Red Dye’ amaranth (Amaranthus) and sunflowers (Helianthus annuus), and mingle beautifully with warm-season grasses. Full sun. Annual.
Collected in August 2020. At least 25 seeds.
