Spent half the morning trying to identify:

East Midlands, south facing rockery, on its own amongst dwarf(?)
strawberries. About 40cm high.

Clues of what to enter on which recommended plant ID site would be
most welcomed too.

So to the subject what is it? Wife thinks it is quite pretty and
wants to leave it in.
