Richard Bolli published a monograph in 1994 titled, "Revision of the Genus Sambucus", in it he proposed the placement of 5 species of elderberry as subspecies of Sambucus nigra, including S. caerulea, Blue Elderberry, to S. nigra ssp. cerulea (note spelling) and S. canadensis, American Elderberry, to S. nigra ssp. canadensis. This change has been accepted by the Integrated Taxonomic Information System (ITIS), but certainly not all taxonomists, see https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4859216/ .
- 'Acutiloba' (sometimes listed as 'Laciniata', (see 'Laciniata' vs. 'Acutiloba' ) – This cultivar “is the counterpart of the cut-leaved form of the European Elderberry but is more graceful owing to the longer and more divided leaf, which is dark green (Trees and Shrubs Online, National Dendrology Soc.). It was released to nursery commerce as a cut-leaved American Elderberry in about 1916 by the Ellwanger & Berry Nursery, Rochester, NY.
- 'Aurea' - golden yellow leaves with cherry red fruit.
