We are so lucky to be able to grow special things like this here in Cornwall ! The red colouring in mine flares up even brighter late summer and the contrast of it's blue flowers in the heart of these red leaves is quite astonishing . In the right place it can spread quite a bit ( it takes a very long time though ), you could split it up , yes it is a bit tough, so wait till we,ve had some rain . It would be a shame to get rid of it .
