This shrubby harbinger of spring can grow 15-20 ft. tall, with many long, slender stems. The pendent, green and white flower clusters - male and female on separate plants - appear just before the thin, pale green leaves. Both flowers and leaves are out long before those of most other deciduous shrubs in the area. The plums in fall are olive-sized purple berries.
