Light. Grows in full sun to deep shade, making it a flexible groundcover.
Water. Water while it establishes. After that it is extremely drought tolerant. Overwatering is the main cause of leaf and root problems.
Soil and feeding. Well-drained soil is a must. It tolerates alkaline, acidic, sandy and clay soils.
Size. Grows 1–2 ft tall in dense, spreading clumps.
Pruning. Little pruning is needed. Divide crowded clumps, and pull seedlings that come up outside the bed to keep it contained.
Problems to watch. Caterpillars and mites can be a problem. Root rot and leaf spot appear mainly on irrigated plants.
Good to know. The sap can irritate skin, so wear gloves when handling it. It is toxic to people and pets if eaten.
