Dwarf Strawberry Tree. Arbutus unedo is a small relative to the native arbutus tree. Grow as a tree to establish a clean trunk. Fabulous shaggy cinnamon bark. Clusters of small white urn-shaped flowers appear in the fall. The fruit develops slowly and becomes ornamental almost a year later when the fruits open to bright orange-red then strawberry-red and hold in winter. Grows 6' x 6'.
