Sedum sieboldii is a low, spreading species that forms a rounded mound, sending out horizontal branches from the central crown. The ¾" round, blue-green leaves are borne in 3's around the stems and each leaf is narrowly outlined in deep pink. During the hot summer months, this 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 sited properly, the foliage turns beautiful shades of pink, red, yellow, and orange. Often, the plant is still flowering when its fall coloring begins to appear.
