Gomphrena globosa
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.

Gomphrena globosa is native to Central America including regions Panama, and Guatemala, but is now grown globally. 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. The plant fixes carbon through the C4 pathway. At maturity, the flowerheads are approximately 4 centimetres (1.6 in) long and the plant grows up to 24 inches (61 cm) in height.
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.
