Hi Daniel, Welcome to ATP!
I don't grow
Baby Sage (Salvia microphylla 'Berzerkeley') so I can't help much. There is growing information in the ATP database (highlighted link above) but nothing that says deer resistant. I have a feeling the deer would like Berzerkeley as much as other salvias. Maybe someone who has experience with this cultivar will pop in soon with some advice.
Again,
I hope you take time to browse some of the forums here at ATP. Pop in and introduce yourself; we have some very knowledgeable members always willing to answer questions and help when possible.
