Moonglow is a perennial succulent of the genus Crassula in the Crassulaceae family. It is a hybrid of Crassula deceptor and Crassula falcata of the same genus. The growth rate is slow. Their leaves are gray-green all year round, closely arranged in layers and decussate. The leaf blade is slightly downy, with small green dark spots on the leaf surface. When you look down on the plant, the leaf blade composition is nearly square. And the side view is like a tower. In low light, the leaves are elongated and spaced out. It has creamy white flowers (five petals) in clusters and umbels. The plant inherits the pale gray-green hue and the fine tomentum of the leaf surface from the parent (Crassula perfoliata var. minor), as well as the dense arrangement and rounded shape of the leaves.
