Thimbleberry berries are known for a burst of sweet/sour taste that is richer and more tart than raspberries. Both flowers and berries are fragrant. Flowers are large, and appear in clusters of 3 or 4 white blossoms. Berries were eaten fresh and made into jellies.

Grows 2-8 foot tall in USDA Zones 3-8. Makes a great addition to woodland gardens and borders. Spreads by under ground roots that form dense thickets. Plants are totally thornless. Large, soft, maple looking leaves are a great contrast to finer leaved shrubs. As a bonus, leaves turn a bright, golden yellow color in Fall. Grows best in rich, organic, acidic, moist well-drained soils in full sun to part shade. Requires regular moisture. Plant 3-4 foot apart.
