Schwarzer Holunder
There are several other closely related species, native to Asia and North America, which are similar, and sometimes treated as subspecies of "Sambucus nigra". The blue or Mexican elderberry, "Sambucus mexicana", is now generally treated as one or two subspecies of "Sambucus nigra" subsp. "canadensis" and "Sambucus nigra" subsp. "caerulea".
