Sedum furfuraceum

An unusual wee plant making neat mounds or carpets of tiny, fleshy leaves condensed along almost woody stems. The leaves are dark green but overlaid with a mealy white farina and appear grey, sometimes red-tinged at the tips. It's a nice effect. Heads of white, pink tinged flowers in summer are almost a bonus. Only 5 to 7cm high (2" or 3").

Although this hails from Mexico, it is remarkably hardy. It is slow-growing so ideal in a hot, sunny trough. Would also make a nice specimen in the alpine house or cold frame.
