Boldly colored. Drought-tolerant. With the wonderful world of succulents, you can mimic an underwater look with plants
Echeveria subrigida ‘Fire and Ice’
Leaves with red edges and a nearly iridescent sheen make this succulent appear to glow like a seastar in a sunlit tidepool. Echeverias tend to stretch with too little light, so give this large (18-inch-wide) echeveria sun or bright shade. Here, a colony of ghost plants (Graptopetalum paraguayense) surrounds it.
