Gomphrena sp is a plant native to Central Tropical America and belongs to the Amaranthaceae family. This delicate groundcover is low-growing, usually reaching a height of 2 feet. It usually flowers in shades of pink, white, off-white, blue, lavender, purple, red, crimson, vinous and yellow, orange. The blooms attract hummingbirds and butterflies. Gomphrena is a very easy to grow and maintain plant, requiring full sun and regular water. Once established, gomphrena is drought tolerant and only needs moderate watering. Generally, it grows well in zones 9-11 of the USDA Hardiness Zone.
If growing Gomphrena in cold areas and in pot, it's best to choose a sheltered spot that gets at least 4 or 5 hours of sunlight each day. It is also better to wait to plant after the last frost of the season to ensure the best results. During the growth season, the soil should be kept moist and even damp. Fertilization is required when planting the seeds and monthly thereafter during the warmer months with a balanced fertilizer. Once the blooms start to appear, deadheading is necessary to boost the flowering and prolong the blooms. In case the climate is too cold, the plant should be moved indoors before the cold weather arrives to prevent damage. It can be kept as a houseplant and brought back outdoors when the temperature outdoors is warm enough.
