I have had Monarda deer damage in the past. Actually not that far in the past, this spring. I moved some Monarda fistulosa at the park and it got browsed to the ground. Mostly Monarda has been untouched though. One thing I've seen is that newly transplanted plants of types not usually considered deer food will often be hit when they are young. Monarda is one and Seaside Goldenrod is another.
