CommentsOther common names for Widow's Cross (Sedum pulchellum) are Limestone Stonecrop and Rock Stonecrop. Widow's Cross is normally an attractive little plant with pink flowers. It is one of only a few native Sedum spp. that are found in the rocky hills of southern Illinois and the surrounding area. Several species of cultivated sedums from Eurasia occasionally escape and naturalize in open disturbed habitats, but they usually don't persist (with the exception of Sedum acre). Widow's Cross can be distinguished from these other species by its pink 4-petaled flowers, widely spreading branches of its inflorescence, and small linear leaves that are nearly terete. Other sedums often have white or yellow flowers, flowers with 5 petals, inflorescences with ascending branches, or leaves that are more flattened and wide than those of Widow's Cross.
