This beautiful form of rock garden sedum was discovered on a volcanic island off the coast of Korea. Serrated foliage forms bicolored rosettes of green and cream, becoming tricolored when the cooler temperatures arrive in fall. At that time, leaves will get a pink blush to the edges. Yellow blooms appear midsummer and are held just above the foliage. This sedum creates a dense mat, perfect for covering slopes and other trouble spots in sunny areas.
