It may be a plicatum but it's NOT a tomentosum! Check out Viburnum plicatum var. plicatum 'Kern's Pink'. ('Roseum' has more maple-looking leaves and oddly enough, bright white flowers!) Here is a link that might be useful: Viburnum 'Kern's Pink'

Based on the leaf shape, it seems they would be V. cassinoides (now consider V. nudum var. cassinoides), V. lentago, V. rufidulum (usually has shinier leaves though) or V. prunifolium. Both V. lentago and V. prunifolium can reach the size of a small tree (V. rufidulum can too but I don't think that is what you have). V. cassinoides seems to max out at about 6 feet based on some sources.

Bellarosa, my VV has never had a problem with blooming. It is just that in the three years I have had it, it hasn't really gotten very tall and turned into a monster as far as overall size. Most of the type III viticella clematis that you purchase can become a monster in size if you don't prune it down each year ( also provided it doesn't get killed back by mother nature during the winter). In Linda Buetler's book, she shows a picture of Polish Spirit that had never been pruned back and is climbing a tall evergreen tree of some sort. The only problem with doing that is that the plant flowers on new wood so any old wood shouldn't have any flowers and the older woody growth may loose its foilage and become leggy. I may have to try not pruning my VV this year and see what happens to it though! I love a good experiment! Annie, it sounds as if your viburnums would work wonderfully for D of A. The plant will take a few years to get established and really get going and if you keep it pruned back the first year or so to establish a good root system, it shouldn't overwhelm your plants and give them a chance to get growing. As far as how big D of A might get, I will leave that to be answered by someone who has had theirs longer. Mine has been in the ground for only three years and is on the north side of the house. Good luck!

I think you're right!!!!
