They have an eight month growing season here--October through May--so we wind up chopping back and feeding several times a year. Maybe not so often in the UK, but a pinch early on could easily triple the number of growing points, and so the number of blooms.

I always nip the tips of mine and I dead head all summer to keep them coming.
