Viburnum dentatum
Viburnum dentatum (Southern Arrowwood) sold by the local soil and water conservation district as Viburnum rafinesquianum. I bought 25 of them (dormant and bare root) and most survived the transplant, deer, and rabbits. it was when they leafed out that I began to suspect something was not right. Viburnum dentatum does grow in a single place in my county down in the southeast corner according to a very old record by Olga Lakela. According to Minnesota Wildflowers this species is not native to Minnesota. https://www.minnesotawildflowers.info/shrub/downy-arrrow-wood
The leaf underside of Viburnum dentatum is glabrous while those of Viburnum rafinesquianum are covered in soft hairs (downy"). Other differences between Viburnum dentatum and Viburnum rafinesquianum are in the fruit (a drupe) which is blue and round in the former and dark blue to black and somewhat flattened in the latter. Also, Viburnum rafinesquianum has a pair of thin stipules at the base f the petiole while Viburnum dentatum does not.
