Pineapple sage

Pineapple sage, recently added to my garden, is turning out to be kind of a disappointment. It doesn't look like a sage, it doesn't smell like a sage, it's growing much too fast and out of the space it's been allotted.

I googled it, and the plant I have fits the description as to leaf shape and texture.

It seems to me that it's not a real herb -- that is, I can't see that it would be much good for cooking or salads. As a smudging plant, I sincerely doubt it.

Anyone have any ideas what the heck it is?

This is one of my favorite herbs, actually.

If a person expects it to be like regular sage, they will be disappointed or confused.

It grows large fast with no coddling.
The leaves have a nice sweet pineappleish flavor- good chopped in some dishes, and good for a tea (if one cares for the taste). The attractive (if one cares for them) flowers are also edible, quite sweet.

It works well in a pot to prevent growing out of control.

As for what it is- the sweet flavored sages have an origin from central america, as opposed to the european and asian origins of most "common" sages. (Salvia divinorum, a hallucinogen which is also very different (!) from common european sage also is of central american origin.)
There is a wide variety of plants which have been called sage.

Real herb is in the eye of the beholder depends on what one wants to use it for. I myself have never liked the widespread attraction to "smudging" but many do, obviously.
