Questions

Perennial Salvia questions, answered straight.

Do deer eat perennial salvia?

Rarely — perennial salvia is considered deer-resistant, which makes it one of the safer unfenced choices in deer country. Hungry deer in a hard winter test every rule, but it's a low-risk pick.

Is perennial salvia safe for kids and pets?

Perennial Salvia is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.

How do you propagate perennial salvia?

Division or seed.
