Gardening with Thimbleberry: This thicket-forming shrub needs virtually no special care, beyond space and a little tolerance on behalf of the gardener. It will thrive in moist or dry soil, from full sun to full shade. Its oversized, soft textured leaves make a bold contrast in the garden and turn a bright, golden yellow in fall. It is especially attractive on hillsides with dappled shade, where they will help control erosion. Be sure to give it lots of elbow room, as it wants to form a large, bramble overtime. Sacrifice part of your yard to this plant and you’ll be generously rewarded by its abundant floppy white blooms, massive insect and wildlife benefits, and edible berries.
