Bob Hornback found this interesting form of thimbleberry. Instead of the usual single white flowers, this cultivar offers double flowers. The extra petals are a nice touch against the background of large velvety leaves. Thimble-shaped edible berries follow which are mild flavored but sweet and much enjoyed by birds. Grows 3 - 6 ft. tall and spreading. Needs part shade and moisture.
