Viburnum rudum 'Winterthur'
Now available even in the Big Boxes, this Viburnum is loved for its just-right size (to 5 or so feet tall and wide), perfect shape, and gorgeous fall color, berries included.
Though the species is native to all of the Eastern U.S. those single quotes tell us that Winterthur is a cultivated variety, meaning it's not really native anywhere.
Oh, about those berries. Turns out it needs an appropriate mate nearby to bloom and berry. I grow just one, so its boyfriend must be some other Viburnum in my garden or a neighbor's, one that blooms at the same time. Here's a terrific discussion about how to find the right pollinator for your Winterthur.
