I dont believe there are any plants that are deer resistant.If deer are hungry they will eat anything.
Generally I think they leave salvias alone,might be the scent.
I saw 10 deer last night.I thought we only had 4.They come thru the yard regularly and eat the birdseed,Hydrangeas and Heucheras or anything that sticking up thru the snow.
I used to freak out but regular repellent spraying starting March ,keeps them out of the garden all summer.
