Autumn Joy Sedum explodes into massive, flat-topped flower heads that start soft pink and slowly transform into deep rose, then rich copper-bronze as autumn arrives. Those flower clusters look stunning against its thick, succulent gray-green foliage, and they stay beautiful for weeks. Even after the blooms fade, the dried seed heads turn a handsome rusty brown and stand tall through winter, catching frost and snow like natural sculptures. It gives you three seasons of interest from one tough plant.
