Salvia leucantha

Gorgeous. For me this is a bit tender, our big frosts knock them down.

Mexican Sage. From there and Central America. it tolerates occasional light frosts and temperatures down to about -8°C, but above-ground growth will die back. It thrives in full sun and requires excellent drainage to survive the cold, wet winters here with me. I like to do a few cuttings as insurance. Only young, keep out of the frosts this winter. 0.8 x 1m

Best to go to you in spring. Do not put out into frosts until next year.
