The genus Gomphrena was first described by Carl Linnaeus in 1753. The name is derived from the Greek word gomphotheres, meaning “to bear balls”, referring to the round flower heads.

How to plant and care for Gomphrena

Gomphrena can be direct-seeded into the garden after all danger of frost has passed. They can also be started indoors 4-6 weeks before transplanting out. Sow seeds on the surface of a well-drained, sterile seed-starting mix and lightly cover with vermiculite. Keep the soil moist but not wet and at a temperature of 70-75 degrees F until germination, which will occur in 10-21 days.

Uses for Gomphrena

Globe amaranths are most commonly grown as ornamental plants. The flowers can be dried and used in arrangements, or the entire plant can be cut and used as a fresh or dried flower. The flowers are also sometimes used in leis.

Propagating Gomphrena

Growing Gomphrena in containers

Cut flowers can be harvested when they are just beginning to open. Flowers can be stored in a cool, dark place for up to 2 weeks. To dry flowers, cut the stems and hang them upside down in a dark, well-ventilated room. Dried flowers will retain their color and shape for several months.
