Rose moss is not one plant. It’s a name that's used for several plants in different places. The best-known is the moss-rose portulaca (Portulaca grandiflora). This low, spreading annual forms a cushion and blooms with small, bright flowers in many colors—pink, red, orange, yellow, and white. In gardening catalogs, “rose moss” usually refers to this plant, but the name can be used for other cushion‑forming plants as well in some regions. When buying, check the scientific name to be sure you get the right plant.
