Is Viburnum Trilobum deer resistant
I don't have experience with this plant, but I spent some time doing some research and found that it appears often on "deer resistant" lists:
No plant is 100% resistant, of course, because deer don't have the propensity to starve when there is SOMETHING to eat. So resistant is often related to 1) palatability and 2) available alternative foods. The fruits are certainly eaten by deer and other mammals and birds.
Hope this helps!
