Hot colour

Been trying for ages to remember what this plant is called but so far it's been a question of 'intellectual overload' (Much prefer this phrase to 'senior moment'!) Perhaps someone out there can jog my memory. It's one of the few 'hot colours' I have in the garden.
Managed to get the housework and washing done and some work in the garden this afternoon. Weather been pretty good all day although raining now and forecast not good for tomorrow.
