I bought this on a whim last winter (or maybe the winter before that) from (I think) Forest Farm. Today I finally found it a home. I have been very impressed with this viburnum. The foliage is very lustrous and clean. The flowers were very pretty and atypical for viburnums (not that viburnum flowers are not pretty, btw--please no abusive responses!), and the fruit is very beautiful. Other than this, I know nothing more about how tall or wide this thing will grow. Does anybody know? Also, does anybody know the parentage?
