My Salvia ' Hot Lips' has grown into a big bush too Fermi in just four years and often has predominantly red flowers - it has such a long sustained flowering period though that I do not mind. It is still going strong as we approach winter and at the moment has quite a few pure white flowering branches. It is grouped with a scarlet red variety the name of which I have lost and Salvia elgans so late in the year I have a very colourful patch. Cannot get out to take a 'photo as we are having some torrential, but welcome, rain at the moment!
