Portulaca growswell in poor, gravelly or sandy soil.
At heights of no more than 6 inches, portulaca, also known as moss rose or sun plant, is a low-growing stunner with cactus-like blooms that last all summer. The blooms, in bright jewel tones of orange, pink, purple, yellow, red and white, grow on thick, succulent foliage. Portulaca is cold-sensitive and thrives in hot, dry areas. It is grown as an annual in most climates. However, the plant is perennial in U.S. Department of Agriculture growing zones 10B through 11. Plant portacula in a rock garden, patio container or hanging basket. Once planted, portacula requires virtually no care.
