Sambucus canadensis 'Bob Gordon'. From a wild American Elderberry selection in Missouri, Bob Gordon is now a prime variety in the US elderberry-growing industry. With large flower heads and fruit clusters, and its tendency for fruit to droop upside down when ripe (deterring birds from eating them), this variety is particularly valuable. You can choose to cut the bush to the ground each winter to control its size and each year it will produce fruit on first year wood. May reach 8' but can be managed at 6'. Berries are used in medicine, and flowers are used as a gourmet flavoring and in cooking (batter them!). Plant a different variety of S. canadensis for pollination. Zone 3.
