American Cranberrybush (Viburnum trilobum )
Many authorities, including USDA and BONAP, lumped these two together under one name, Viburnum opulus. We have separated the two, per BONAP's treatment; this taxon refers only to populations native to North America; in this treatment, the European cranberrybush (Viburnum opulus), only includes populations introduced from Europe.

This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.
Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.
We marked the Nebraska population introduced because it probably originated from garden escapes, and, although it is only separated from the native population by a small distance, the new population is south of the native range and this species is uncommon along the southern border of its range and shows no evidence of expanding southward, leading this population to be isolated and probably stay isolated. We will update our map if we see any evidence of this changing. This species is also native to Canada, but we have yet to build this portion of its range map.
