Gomphrena globosa Globe Amaranth

Edward F. Gilman and Teresa Howe


Globe amaranth produces small, globe-shaped flowers in shades of purple, pink, yellow, or white (Figure 1). The purple form is most common in retail nurseries. Most horticulturists utilize globe amaranth in a mass planting spacing them 12 to 18 inches apart. Others use them as small specimens in rock gardens or plant them in containers. They are also attractive planted in a row along a walk or patio as an edging plant. Flowers can be dried for indoor use if cut just before they are fully opened. The plant grows 18 inches tall and prefers full sun and a moderately dry soil. Globe amaranth is resistant to heat and should not be over watered. It provides bright color to a garden or landscape where irrigation will be limited.
