Also known as Globe Amaranth, Gomphrena brings a burst of color and charm to any sunny garden. Native to Central and South America, Gomphrena is beloved for its vibrant globe-shaped blooms, long-lasting color, and incredible toughness. Heat- and drought-tolerant once established, it’s one of the most dependable annuals for Upstate South Carolina gardeners — thriving from spring through frost with minimal care.
Our Selection of Gomphrena
At Martin Garden Center, we carry several different varieties of Gomphrena in the Spring. The “Ping Pong” series has white, pink or purple globes and this cultivar ranges from 8-12 inches in height. In 2023, one of our customers came in and bought 65 of the purple variety. WOW. We also carry Proven Winner Truffula Pink Gomphrena, which grows 20-30 inches in height. After several years of searching for Strawberry Fields Gomphrena and being thwarted because none of the growers in our area carry it, we bought seeds so we will see the gorgeous red blooms of Gomphrena haageana, or Strawberry Fields.
We are finding that Gomphrena are gaining in popularity. In 2024, we sold out rather quickly and we could not locate Gomphrena from our vendors. So if you want this easy to care for prolific blooming plant that makes an excellent cut flower, shop in the early Spring.
We are growing the following varieties in 2025:
- Ping Pong Purple – Compact (8–12”) plants with dense purple globes. Perfect for borders and container accents.

How To Grow and Care for Gomphrena
Gomphrena thrives when planted in a location that receives full sun throughout the day. For the best flowering performance, these plants need at least 6 to 8 hours of direct sunlight daily, although they often bloom even more heavily when given all-day sun. Insufficient light can lead to weaker stems, reduced flowering, and a more stretched growth habit. When planting, allow at least 12 inches of spacing between plants to promote good air circulation and accommodate their mature size, which can reach up to 2 feet tall and about 1 foot wide depending on the variety. Proper spacing also helps reduce the risk of fungal issues during periods of high humidity.
Gomphrena performs best in well-draining soil enriched with organic matter such as compost or aged pine bark. While it adapts to a wide range of soil types, it struggles in heavy, poorly drained soils where excess moisture can lead to root problems. Once established, Gomphrena develops a strong root system that allows it to tolerate challenging growing conditions and continue blooming through the heat of Summer.
Consistent moisture is most important during the first few weeks after planting while the roots are becoming established. After that point, Gomphrena becomes quite drought tolerant and can often withstand periods of hot, dry weather better than many other flowering annuals. During extended dry spells, occasional deep watering will help maintain vigorous growth and encourage continuous flowering. Applying a 2 to 3-inch layer of mulch around the base of the plants helps conserve soil moisture, regulate soil temperatures, and reduce weed competition.
Although Gomphrena is not considered a heavy feeder, incorporating a slow-release fertilizer at planting time can support healthy growth and flowering throughout the Season. Deadheading is generally not required, as the plants naturally continue producing new blooms without much intervention. One of the reasons I like Gomphrena so much is its durability. It handles heat, humidity, and drought exceptionally well while remaining attractive for months.
Gomphrena is relatively disease and pest-resistant, but it’s still a good practice to monitor for any signs of pests and address them if necessary. Occasional inspections for aphids, spider mites, or signs of fungal issues are always a good idea. With minimal maintenance, Gomphrena will provide a steady display of colorful blooms from late Spring until frost.
Leaves and Flowers
The distinctive globe-shaped blooms of Gomphrena are composed of papery bracts rather than petals, giving them a unique, long-lasting texture. Colors range from bright magenta and deep purple to pure white and fiery red, often retaining their vibrancy even after drying.
The foliage is green and lightly fuzzy, forming a bushy backdrop that highlights the rounded blooms. Some varieties feature subtle color variations or silvery undertones on the leaves.
Gomphrena blooms continuously from late spring to frost, without the need for deadheading. Their everlasting nature makes them perfect for dried arrangements — retaining color for months or even years indoors.

Frequently Asked Questions
Do Deer Eat Gomphrena?
Deer typically avoid feeding on Gomphrena plants due to their texture, taste, or scent. The tough and slightly fuzzy nature of the leaves, as well as the overall characteristics of the plant, make it less appealing to deer.
Should You Pinch Gomphrena?
Pinching can be done to encourage bushier growth and more compact plants. This involves removing the tips of the young stems, stimulating lateral branching and resulting in a fuller, more well-branched plant.
Does Gomphrena Need Light To Germinate?
Gomphrena seeds do not require light to germinate. In fact, these seeds typically germinate best when sown in darkness or covered with a thin layer of soil. While some seeds benefit from exposure to light for germination, Gomphrena seeds do not fall into this category.
