Echeveria agavoides ‘Ebony’ is a succulent plant that forms clusters of up to 12 inches (30 cm) wide tight rosettes of fleshy, gray-green leaves that have vivid red edges most pronounced toward the dark red terminal spine. Echeveria are very popular succulents that grow in attractive rosettes with beautiful leaves in a variety of colors and sometimes stunning flowers. These plants have been extensively hybridized, so in addition to the main species there are many varieties that have been specially bred for interesting leaf form and color.
