Salvia from Guatamala

This lovely Salvia was discovered in Guatemala by the owners of Crug Farm Plants, North Wales, a few years ago. It is yet to be identified.......of course it may be a hybrid.... as it has never set seed here, to my knowledge. It is a tall, rather leggy plant, which requires some support. It flowers in mid-winter, and just about survives in my greenhouse. Flowers are plentiful, if short-lived. I do wonder if Salvia mexicana is involved somewhere. Whatever it is, I like it very much, and it is a truly reliable Salvia to provide colour in winter, in the greenhouse.
