This salvia is one of the many American crosses of salvia oresbia (darcyi) and microphylla.  It flowers orangey scarlet in warm weather.

‘Silke’s Dream’ will grow up through a light bush or could be grown through mesh to 1.5m.   Otherwise it could be pinched to keep it a compact shrub.   Because of its straggly growth I am not going to continue on with this plant and suggest you buy oresbia (darcyi) instead.  The flowers are a bit redder but the growth is more pleasing.

Lambley Perennials grew quite a lot of it in the summer of 2013/14 which I thought was rather an odd choice as it needs quite a bit of pruning.

It is reasonably cold and drought hardy .   It would have to be grown as a cutting to be sure to have an identical plant.
