Sedums are almost the perfect plants. Vigorous, carefree, good-looking, with a season of interest lasting more than 6 months, who could resist? Even the bees and butterflies can't! These standout perennials grow more or less erect, up to 2 ft. (60 cm), and form a clump of thick, fleshy sage green to blue to dark red foliage topped with flower buds resembling broccoli. Gradually, these densely clustered buds reveal tiny, star-like flowers, in shades of white, pink or red, in late summer or early fall. As the weather cools, their colors grow deeper and richer. Both foliage and dead inflorescences remain attractive through winter, providing some additional interest.
