Native to (or naturalized in) Oregon:
- Broadleaf deciduous (nearly evergreen mild climates) tree or large shrub,15-30 ft (9-15 m) high, may form a thicket, has pithy stems. Leaves opposite, pinnately compound, 15-25 cm long, 5-7(9) leaflets, each 5-15 cm long and 1-5 cm wide, narrowly ovate or lanceolate, unequal at base, coarsely serrate, bright green (a variable species). Flowers yellowish-white, 5-lobed, 6 mm wide, in many branched, flat clusters. Fruit 6 mm, dark blue with whitish bloom, edible, but not very palatable fresh. When cooked makes a good jam, pie, and wine.

- Hardy to USDA Zone 4 Native from British Columbia east to Montana and Utah, south to California and New Mexico. Shrubs in the genus Sambucus are the only ones found in the Pacific Northwest forests that have both opposite and pinnately compound leaves.
- Richard Bolli published a monograph in 1994 titled, "Revision of the Genus Sambucus", in it he proposed the placement of 6 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/ .
