|This is an arching, very thorny, thicket-forming, deciduous shrub with attractive white winter shoots. Leaves are pinnate, to 8" long, with up to 9, ovate, glaucous leaflets. Purple, saucer-shaped flowers, to 1/2" wide, are held in terminal racemes and borne in summer.
Fruit is black, round, to 1/2" in diameter, and has an unpleasant taste. Grows to 8' tall and wide. Native to China. The Rubus genus is made up of flowering, and better yet, fruiting (yum) shrubs, including raspberries and blackberries, that may or may not have thorns.
There are both native and ornamental selections, some evergreen, some deciduous. Most brambles do well in full to partial sun and tolerate infrequent watering.
