California blackberry
Also known as: boysenberry
A woody deciduous shrub of long arching canes which will root and form a prickly thicket, if left untrained. The leaves are green and the flowers white and fragrant. The plant has separate male and female plants so will both both sexes will be needed for good fruiting. Other members of the family nearby may also pollinate it successfully. The fruit is small but sweet and forms decorative clusters at various stages of ripening - red through to black. Good pollen source for pollinating insects
