Favorite or New Plant
A favorite sedum that grows in poor soils and withstands heat and drought is the stonecrop (Sedum acre). Its fleshy foliage remains attractive in all seasons, with subtle changes in color in fall and through winter. The flowers are borne in terminal clusters of shortened spikes or flattened heads. Depending upon the variety, blooms can range from yellow, white, pink, rose, purple, and red. They do best in full sun and very well-drained soils.
