Another Salvia?

This looks (spikes of blue flowers attracting pollinators, slightly hairy, slightly grey leaves) and smells (sage) like a Salvia but I'm confused by the toothed leaves. Anyone know what variety it is, please?
Thank you!

That looks like Perovskia to me (I was taking cuttings from mine the other day). It is sometimes called Russian sage, but I don't know if they are actually related.

Another (same) suggestion from our social media:

"Perovskia atriplicifolia or Russian Sage (not technically a sage?). Love this plant, the smell as you brush past. Bees love it too, more popular than lavender in my garden."
