Sedum sieboldii is often described as having the most beautiful foliage and form of all sedums. It is a low, spreading species that forms a rounded mound, sending out horizontal branches from the central crown. The small round, blue-green leaves are borne in 3s around the stems and each leaf is narrowly outlined in deep pink. During the hot summer months, the pink edge intensifies. In early fall, bright pink, star-shaped flowers are borne in small clusters at the ends of the stems. One of the most beautiful features of this perennial is its fall color. When grown in full sun the foliage turns beautiful shades of pink, red, yellow, and orange. Often, the plant is still flowering when its fall coloring begins to appear. This versatile plant can be used as a small-scale groundcover, as an edger, in rock gardens, or tucked into cracks in a rock wall. It also pairs well with other fall flowering perennials in containers.
