Nannyberry (Viburnum lentago)

Leatherleaf Viburnum (Viburnum rhytidophyllum)

In NJ, in my experience, while this species is sometimes found in overgrown natural areas, it's generally there because it was previously planted. I've never seen it escaped.

Korean Spice Viburnum (Viburnum carlesii)

Planted, not escaped in NJ (that I know of)

Doublefile Viburnum (Viburnum plicatum)

planted, not escaped in NJ. Also called Snowball Viburnum

Maple-Leaved Viburnum (Viburnum acerifolium)

Linden Viburnum (Viburnum dilatatum)

Blackhaw (Viburnum prunifolium)
