Light. Prefers full sun but grows in partial shade.
Water. Drought tolerant. The vines wilt when they need water, so water when you see that.
Soil and feeding. Plant in loamy, well-drained soil high in organic matter. In containers, use a quality potting soil.
Size. Stays about 1 ft tall and spreads 3–5 ft as a groundcover, or spills over the edges of pots and planters.
Pruning. Trim it whenever it gets too wild. The cuttings root in 4–5 weeks and make new plants.
Problems to watch. Serious problems are few, though fungal disease can occur.
Good to know. It grows as a perennial in Florida and thrives in summer heat. The foliage springs back quickly after a frost or freeze. Colors range from chartreuse to near-black purple. It is listed as non-toxic to cats and dogs.
