It is drought tolerant and salt tolerant, making it a hardy and easy-to-grow plant. Aside from being nice and lush, Perennial Peanut also gets a yellow flower that makes it very attractive.
How to care for Perennial Peanut
Light. Flowers best in full sun. It also grows in partial shade.
Water. Water regularly while it establishes. After that it resists drought.
Soil and feeding. Handles Florida's sandy soils and needs little fertilizer.
Size. A low ground cover about 6 inches tall. Space plants 12–18 inches apart to fill in completely.
Pruning. Mowing established plants makes them bloom more, but it is not required. Use metal or fiberglass edging to keep the rhizomes out of beds.
Problems to watch. It resists nematodes and diseases. It takes only light foot traffic, so add stepping stones along paths.
Good to know. Evergreen in frost-free areas. Its mat of rhizomes helps hold soil on slopes. Start new plants from cuttings.
