Vanessa,
I sympathize with you on the wild animal population. I have no clue about what that would be like and do not care to think about it, just gives me a headache! Jeepers.
There is a thread here on the perennials forum about deterring deer and the best suggestion we heard was one about stringing fishing line around poles or trees. The deer cannot see the line and get spooked by it. The phrase was 'Feet don't fail me now!' LOL.
Check on the hostas you might be surprised, I found most of mine for sale in the north not the south. They have them and do not even know it.
