Gomphrena globosa
Also called Globe Amaranth, Bachelor's Button, Globe Amaranth, Bachelor Button
Globe amaranth is a heat-loving tropical annual grown for its round, long-lasting flowerheads that keep their colour when dried. It thrives in full sun and is fairly drought tolerant once established.
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.
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.
In Hawaii, it is commonly used in long-lasting leis since it retains its shape and color after drying.
