Echeveria subrigida is an attractive succulent plant. It forms rosettes of fleshy, spade-shaped leaves that can reach a width of up to 38 cm (15 inches). The leaves are up to 9 inches long, creamy aquamarine and are highlighted with a thin rosy-pink border. Starting in May, up to 30 cm tall spikes rise from the center of each rosette, producing cymes of milky-blue buds that gradually age to tubular coral flowers. Orange tones inside add to the charm of these up to 1 inch long blooms. Flowering will often continue most of the summer.
