Sambucus canadensis 'Nova'. The Nova Elderberry is an easy to grow, beautiful and medicinal plant, pairing well with the other American elderberry varieties for pollination and to stagger your harvest. Grows to about 6'. Berries produced on first year wood, so heavy pruning is common and recommended. Used for everything from cough syrup to making a divine liqueur. American elderberries are native to North America. Use another S. canadensis cultivar as a pollinizer. Zone 3.
