Sedum Spectabile are succulent perennials native to China and Korea and are often called Stonecrop. Many cultivars exist, but Autumn Joy is one of the best-loved. It was introduced by German plant breeder Georg Arends in 1955 as the result of crossing Eurasian Hylotelephium with the Chinese/Korean Hylotelephium Spectabile. Autumn Joy has water-retaining oblong leaves that emerge pale green in late spring on fleshy stalks. In late summer to early autumn, large flat clusters of pinky-green buds open to reveal tiny rich-pink flower stars. As autumn progresses, the flowers mature to deep pink and shades of brown before the whole plant dies down with the frosts.
This pretty and much-loved Stonecrop is sometimes called Sedum Spectabile Herbstfreude (German for Autumn Joy). It has retained an RHS AGM for years and provides months of late summer to early autumn colour.
