Japonica is a small cold hardy evergreen. No prizes for guessing its country of origin! Japanese plants often are found around streams but will take average watering conditions.
Foliage is a tight rosette form with summer flowers on spikes about 25cm from the base. A well grown plant can be pretty. The species appears to have mauve flowers but there is a white form.
Japonica sets seed which grows readily enough.
There are a number of other similar salvias in Japan and China but they may mainly be annuals. We have had, and maybe lost, chienii, in Australia.
