SYMPHORICARPOS albus. This is the familiar snowberry of California creeksides. It can form broad thickets or sometimes narrower fountains, up to 5' high. It has soft, bright green to blue-green leaves, about 1" long on the side shoots but noticeably larger on stronger, suckering shoots from the base. The bell-shaped flowers are only about 1/4" long, light pink or white with a pink tinge. The berries are far showier, swelling to 1/2" and pearly white in color. 'Tilden Park', introduced by the botanic garden of that name (and one of my "most recommended" places to visit) is a bushy selection with bright, clean foliage and a reliably heavy crop of large berries. Sun or light shade near the coast, light shade inland, thriving in many different soils with moderate watering. 10oF. or less.
