Sambucus canadensis — American elderberry — is a North American native shrub that produces fragrant flat-topped flower clusters and heavy clusters of small dark-purple berries used in elderflower cordial, elderberry syrup, wine, and jam. It is native to every state east of the Rockies and is increasingly recognized as a valuable plant for both food production and wildlife habitat.

European elderberry (S. nigra) includes the ornamental cultivars widely sold at garden centers — 'Black Lace', 'Black Beauty', 'Lemon Lace' — which have deeply cut, dark purple foliage. These are grown primarily as ornamental shrubs but technically produce edible berries. For serious berry production, native American elderberry is the more productive choice.

I don't grow elderberry at my Long Island zone 7a plot. This guide is sourced from Penn State, Cornell, and Missouri Botanical Garden.

Safety note: elderberry toxicity

Per Penn State Extension, raw elderberries, bark, and leaves contain sambunigrin and related cyanogenic glycosides that can cause nausea, vomiting, and diarrhea. Cook all elderberries before consumption. Cooking destroys these compounds. Elderflowers are generally considered safe for raw use in cordials and as garnish in small quantities. Never eat elderberries raw in large quantities.

This is not a hypothetical concern — it is the reason elderberry products are always cooked and why raw juice is not recommended.
