Elderberries are an easy to grow, very versatile bushy plant producing delicate white flowers followed by bunches of tiny, bluish-black berries that are very juicy. It's a popular medicinal plant used in a wide range of alternate therapies, most commonly to protect against colds and flus. The berries are too bitter to be eaten by themselves so are often dried, juiced or cooked in wines, juices, jellies and jams.
