I noticed an Allegheny Viburnum growing in my neighbors yard and was quite impressed by the leaves, the shape, and the flower clusters.
Sadly his way of trimming a tree or shrub is to hack half of it down...after seeing this I've been sort of "borrowing" clippings in an attempt to propagate
a few plants for my garden. Hopefully third times a charm because the first two attempts were unsuccessful.

I believe this plant will grow pretty much everywhere. Ubiquitously known as the leatherleaf viburnum, it adorns the corner of new and old homes; makes inappropriate hedges around commercial parking lots (in the mistaken belief that it is a 4' tall shrub -- more like 14' tall); and can screen tall eyesores in a single bound.

This is actually a very nice plant. It is just used incorrectly far too often because people don't understand its ability to just GROW with abandon. Allow for a 20' x 20' plant that blooms white in the spring, sets wonderful red clusters of fruit, blooms again near autumn, and then you'll get the idea.

This hybrid is a cross between the evergreen leatherleaf viburnum, V. rhytidophyllum and the wayfaring tree, V. lantana 'Mohican'. The hybrid is evergreen in warmer areas but semi-evergreen at the northern end of its hardiness range. The leaves are very rough and veiny. The cream flowers develop into fruit that change from red to black.
