Gomphrena globosa, commonly known as globe amaranth, is an edible plant from the family Amaranthaceae. The round-shaped flower inflorescences are a visually dominant feature and cultivars have been propagated to exhibit shades of magenta, purple, red, orange, white, pink, and lilac. Within the flowerheads, the true flowers are small and inconspicuous.[1]

Gomphrena globosa is native to Central America including regions Panama, and Guatemala, but is now grown globally.[2] As a tropical annual plant, G. globosa blooms continuously throughout summer and early fall. It is very heat tolerant and fairly drought resistant, but grows best in full sun and regular moisture.[3] The plant fixes carbon through the C4 pathway.[4] At maturity, the flowerheads are approximately 4 centimetres (1.6 in) long and the plant grows up to 24 inches (61 cm) in height.[1]

Gomphrena globosa is an outcrossing species that is pollinated by butterflies, bees, and other insects. Floral volatiles likely play a significant role in the reproductive success of the plant by promoting the attraction of pollinators.[1]
