Sambucus nigra vs. Sambucus canadensis: European and American Elder

Ask what species your elderberry is and you'll get one of three answers: Sambucus nigra, Sambucus canadensis, or Sambucus nigra subsp. canadensis.

The third one is the giveaway. Those aren't three plants — they're two plants and an ongoing argument about whether the second is a separate species or a subspecies of the first. Botanists have gone back and forth for decades.

For a buyer, the practical differences are smaller than the naming suggests. But they're real, and there's a third species in the genus that genuinely matters for safety.

The Naming Problem

Sambucus canadensis was long treated as its own species. More recent classification reassigned it as a subspecies of the European elder, giving Sambucus nigra subsp. canadensis.

Both names remain in active use. West Virginia University Extension lists them together — Sambucus canadensis, also known as Sambucus nigra subsp. canadensis — and treats them as one plant with two labels. University of Florida's cultivation guide does the same.

Practically: if a label says canadensis in any form, you're looking at American elder. If it says Sambucus nigra with nothing after it, European.

How They Differ in the Field

Size and shape is the clearest difference. WVU describes American elderberry as more shrub-like, growing 8 to 10 feet high, while European black elder has the makings of a small tree and will reach 20 feet.

Range. European elder is native to Europe and has naturalized widely; NCCIH describes it as growing across Europe, North America, Western Asia, and North Africa. American elder is native to much of eastern and midwestern North America — the University of Missouri notes it's commonly found in a range of habitats, often along roadside ditches and streams.

Everything else is nearly identical. Both have pinnately compound, opposite, toothed leaves. Both carry small creamy-white flowers in flat-topped cymes. Both produce dark purple-black berries. Both have the corky lenticels along the twigs that make elder recognizable in winter. And both require cooking.

Which One Is Grown Commercially

Both, in different places, for practical rather than botanical reasons.

Europe grows Sambucus nigra. It's an established commercial fruit crop there, with cultivars bred over generations for high anthocyanin content — the deep pigment that matters for juice, colourant, and extract production.

The US increasingly grows Sambucus canadensis. The University of Missouri's agroforestry programme concluded that American elderberry appears to be the better candidate for commercial production in Missouri, and much of the American cultivar development — Bob Gordon, Wyldewood, Adams, Nova — sits on this side.

UF/IFAS notes that in the New World, elderberry didn't find meaningful commercial acceptance until recently, having been more of a small-scale or backyard crop, partly because of the challenges of harvest and postharvest processing and reports of the toxic nature of parts of the plant.

That's the honest reason American elderberry is a newer commercial crop: it's laborious to harvest and the safety story scared people off.

Does the Research Apply to Both?

This is the question that matters most, and the answer is a qualified yes with a caveat.

The clinical literature is built on Sambucus nigra. NCCIH's fact sheet uses Sambucus nigra as its reference species throughout, and the trials it cites — including the Hawkins 2019 meta-analysis on upper respiratory symptoms — used standardized European elderberry preparations.

Because canadensis is now widely classified as a subspecies rather than a separate species, the two are far closer than, say, German and Roman chamomile, which sit in different genera entirely. The chemistry is broadly similar.

But "broadly similar" isn't identical. Anthocyanin profiles differ between the two, and the specific standardized extracts used in trials were made from European material. If a product cites clinical research, the honest position is that the research was done on European elderberry.

And the same caveat that applies to every herb applies here: positive trial findings involved standardized extracts at controlled doses, not cups of tea.

The Species You Should Actually Worry About

Neither of the above. The genus contains roughly ten species, and one in particular is a genuine hazard.

Red elderberry (Sambucus racemosa) grows in the northeastern United States. WVU Extension describes it as highly toxic to humans and explicitly not recommended for commercial fruit production — it's grown as an ornamental landscaping plant, with extreme caution warranted due to its toxicity.

Red berries, not purple-black. If you're foraging and find red fruit on an elder-looking shrub, that's a different plant with a different risk profile.

There's also blue elder (Sambucus mexicana), the indigenous elder of the western United States. The CDC's report on the 1983 California elderberry poisoning describes it as growing to 30 feet and producing small, nearly black berries often covered with a white bloom at maturity — juicy and edible when mature, commonly eaten cooked in pies and jams. Edible, but the same cooking rule applies, and it was the species involved in that outbreak.

Does It Change How You Use Them?

No. Every practical instruction is the same for both:

• Cook them, always
• Discard leaves, stems, bark, and roots
• Brew dried berries 15 to 20 minutes at a full boil
• Simmer 30 to 45 minutes for syrup

The only real consumer-facing difference is flavour, and it's subtle. American elderberries are sometimes reported as slightly sweeter than European cultivars. European material tends to be more astringent and more heavily pigmented — which is part of why it dominates in processing.

What You're Buying

Farmer Soul's elderberry is Sambucus nigra, carefully sourced from Eastern European botanical growers and USDA Organic certified. That's the species the research base sits on and the one with the longer commercial track record for processed products.

We name the species on the product page rather than just saying "elderberry," because with a genus this large — and with one member that's genuinely toxic — "elderberry" on its own isn't a complete answer.

Frequently Asked Questions

Is American elderberry as good as European elderberry?

For most purposes, yes. They're now generally classified as the same species, they're used identically, and both require cooking. European material tends toward higher anthocyanin content and is what most clinical research used.

Why do some labels say Sambucus nigra subsp. canadensis?

Because American elder was reclassified from a separate species to a subspecies of European elder. Both naming conventions remain in use, sometimes on the same page.

Which elderberry is used in most supplements?

Sambucus nigra — European elderberry. It has the established commercial processing infrastructure in Europe and is the species the research literature is built on.

Is red elderberry the same plant?

No. Sambucus racemosa is a different species with red berries, described by WVU Extension as highly toxic to humans. It's an ornamental, not a food crop.

Does American elderberry need cooking too?

Yes. Every edible Sambucus species requires cooking. The cyanogenic glycosides are present across the genus, and no species is safe raw.

Can I tell them apart by looking?

Size is the most reliable cue on a mature plant — European elder can reach 20 feet as a small tree, while American elder stays a shrub at 8 to 10 feet. On dried berries, you can't tell at all; you're relying on the label.
