Don't have access to the Plant right now. Are there perennial salvias?

Almost all salvias are perennial.

And some are even evergreen shrubs.

Can you at least tell us where this is growing geographically?

A wild guess given the fuzzy image and the minty smell might be Prostanthera cuneata aka Mint Bush.

Looking at a past post, I believe the location may be Florida.

Mmmm, so possibly not Prostanthera. It might not be hardy enough.

probably not salvia, though they are in the mint family, but salvias tend to smell like cat pee, not mint

-maddyperron if you could take closeup pics of the shrub I am sure you could get a firm ID.

Perhaps a type of calamintha?

I'm guessing Calamintha too. And it's a perennial, not a shrub, despite the woody stems.
