Sedum spectabile 'Autumn joy' is a deciduous perennial that forms a dense bun-shaped clump of fleshy leaves that are dark green with a slightly glaucous appearance.
In colder climates, this bushy clump will die back in winter while autumn brings the attractive flower heads that emerge at the tips of the stems.
The flower heads appear as flattish clusters of soft pink, which eventually age, to a deep red.
If you love sedum, this is a lovely flowering variety for colder climates.
