Sedum x Thundercloud (PP21833) is a dome-shaped cultivar that typically grows in a low mound to 12″ tall and 12″ wide. Pointed, gray-green leaves retain good color throughout the growing season. Tiny, star-shaped, white flowers cover the foliage mound with bloom in mid to late summer. Flowers are attractive to butterflies. Spent flower clusters typically retain shape and add some winter interest to garden areas.

A Northern Sunset Perennial. It prefers average, dry to well-drained soil in full sun to part sun.
