Ripple Jade Overview

Crassula arborescens subsp. undulatifolia, unlike other small Crassula species is an outstanding, squat, succulent shrub that is easily recognizable by its unmistakable wavy, blue-grey foliage, sometimes tinged with red on the edges. Star-shaped, white-pink blooms are produced in clusters. It has a very attractive appearance in both its natural habitat and cultivated gardens. It's also commonly called Ripple Jade, after the leaf appearance. The seeds are very fine and must be harvested as soon as the inflorescence turns brown as the fruit ripens. Many rooted plants will form from the mother plant in the garden when they fall to the ground, provided conditions are suitable.
