Hi Dove, from your link mine looks like it could either, PS36 Stachys officinalis Betony or PS02 Salvia clevelandii Jim Sage, Cleveland Sage.
Its outside but undercover and so quite dry. I'll move into the greenhouse when I get home tonight and re-pot in the spring in gritty soil. I have a great sunny spot for it in the summer.
