Sedum

Sedum is a genus of succulent, herbaceous perennials with fleshy, flat or rounded leaves depending on the species. In general, the plant is upright and spreads along the ground. The genus has over 300 species, though many have been moved to the genus Hylotelephium. Genus name comes from the Latin word sedeo meaning to sit in reference to the habit of many of the sedums species to sit and sprawl over rocks.

It can be grown as a houseplant, ground cover, or interiorscape or landscape. When grown outdoors, most species need sun to part sun. They are easy to grow indoors with bright direct light from a window or grow light. Use a coarse, well-drained soil, preferably a cactus mix. Sedum tolerates rocky and poor soils well, establishes itself quickly, and most species are cold tolerant. The succulent leaves make them drought and dry soil tolerant. They can be damaged by deer.

The taller Sedum species produce large clusters of flowers, in white, yellow, pink, or red and can be used in borders or pollinator gardens. The low-growing species are generally grown for their foliage and spread by rooting stems and work great on a slope, rock garden, ground cover, hanging baskets, and even green roofs. Sedums withstand only light foot traffic. The leaves tend to fall off easily; however, the fallen leaves can be used to propagate new plants.

Diseases, Insect Pests, and Other Plant Problems: Slugs and snails. Avoid wet or poorly drained conditions. Taller sedum species with large flower heads are susceptible to flopping. Site in full sun and pinch back in spring to force thicker stems.
