Why is the globe amaranth, or gomphrena, a favorite among cut flower lovers? Its bright blooms, lasting beauty, and adaptability in floral designs make it a top pick. Let's explore how this tropical beauty can make your arrangements stand out and last longer.
What is a Globe Amaranth Flower?
Globe amaranth, known as Gomphrena, belongs to the Amaranthaceae family. It includes Gomphrena globosa and Gomphrena haageana as main species. G. globosa has stems with clusters of flowers that look like clover. These flowers are actually colorful bracts, not true flowers, giving the plant a unique look.
This plant comes in many colors like pink, purple, red, and white. G. haageana has longer stems and brighter colors. Both types are loved for their long-lasting flowers and ability to grow in hot places.
The Gomphrena globosa plant can grow up to 24 inches tall. Its flowers are about 4 centimeters long when they're fully grown. This plant is originally from Central America but is now grown all over the world. It blooms from summer to early fall, needing full sun and regular water.
This plant needs little water and attracts butterflies. Gomphrena globosa is pollinated by butterflies, bees, and other insects. Its flowers are used in food, cosmetics, and animal feed because of their special chemicals.
Growing Globe Amaranth Flowers
Globe amaranth (Gomphrena globosa) is a vibrant and easy-to-grow annual. It thrives in hot, sunny conditions. You can start it from seed indoors or directly outdoors after the last frost.
For indoor sowing, plant seeds in trays or pots 6-8 weeks before the last frost date. Keep the soil warm at 70-78°F for quick germination. Once seedlings grow, harden them off before moving them outside. Space them 12-18 inches apart in full sun.
You can also direct sow seeds outdoors after the frost danger has passed. Plant them in a shallow trench, 1/2 inch deep, and 6 inches apart. Globe amaranth likes well-draining, moderately fertile soil. It can tolerate partial shade but grows best in full sun.
Once established, globe amaranth needs little care. Just water it and remove dead flowers to keep it blooming. These plants are not often bothered by diseases or pests. But, they might get powdery mildew if watered overhead.

Propagating Globe Amaranth Flower
