No it is isn't, especially in your zone. It is a crap shoot when it comes to survival in zone 7a. Last winter was no measure of survival since most of us had a very warm winter. It is best not to cut it back until you see new life in spring. I have never heard anyone say their Pineapple Sage was invasive. If it does return and the clump is too big for you just dig it up and divide it.

Agree with wardda, this is a fast-growing but would not say invasive Salvia. Golden Delicious obviously recognisable by its golden/lime foliage. Easily controlled, though it will root from prostrate stems, should never be a problem.

My experience with pineapple sages is that the self-layered stems are the most likely to survive, and that applying some mulch for thermal insulation will increase survivability.

I live in zone 7 as well. It is a "tender perennial".
Take cuttings and root them in the fall before first frost.

It "might" survive in your area if you cover it with a big tub. They do NOT like their roots damp in the bitter cold. They like, well-drained, gravelly and sandy soil best.

Not invasive.
