Elderberries are native to temperate to sub-tropical regions of both the Northern Hemisphere and Southern Hemisphere. The leaves are pinnate with 5-9 leaflets. Each leaf is 5-30 cm long with serrated margins. Clusters of small white or cream-colored flowers are born in late spring, followed by clustered of small, black, blue-black, or red berries.
The berries are a favorite to birds and have many health benefits to humans. The ripe elderberries can be made into extract, syrup, pie, jam, jelly, or use as topping, as a dye and for flavoring.
