Chinese Sweet Plum
Chinese Bird Plum
Sageretias are tender shrubs with small green leaves and leathery exfoliating bark that leaves a multicolored patchwork. In summer tiny flowers appear in the leaf axils of new shoots and produce large clusters of white followed by small blue stone fruit. If a Chinese Sweet Plum is pruned too often, the flower buds will be removed and it will not flower.
Sageretias are evergreen in milder climates but become deciduous in temperate zones when exposed to the cold of winter. Sageretia are very rarely seen for sale in Garden Centers. Chinese sweet plum has a tendency to climb and is difficult to control as an ornamental plant. The growth is similar to Pyracantha. There was one growing in Daffin Park, but it was removed a few years ago. Branches have spines, sharp thorn tips.
