In the garden
Sedum aizoon is a non-woody succulent from north Asia that produces upright stems to roughly 0.4 m. It belongs to the Crassulaceae and flowers in the UK from June to September. Plants survive cold UK winters at H7, which means they are fully hardy in exposed and sheltered sites alike; the equivalent USDA hardiness range is 4–10. Place this stonecrop in a sunny position and give it a free-draining substrate. It accepts sandy, loamy or clay soils provided they drain; descriptions of its preferred moisture include well-drained or moist but well-drained conditions, so avoid waterlogged ground. In cultivation allow the surface to dry slightly between waterings when grown in containers, and protect from prolonged winter wet where drainage is poor. Use Sedum aizoon where a low, sun-loving succulent fits the scheme: rock gardens, gravel beds, the front of a sunny border or in pots on a sunny patio. Observe caution when pruning or dividing, as the sap can irritate skin and the foliage is mildly toxic if eaten, so wear gloves and other protective equipment when handling.
