Montbretia- Diagonals

My photography course 'A Year With MY Camera'  also  AYWMC ha started a challenge for August called 30 days of composition. Today's prompt is diagonals, so here is my effort. I've always called this montbretia, but I think it's also crocosmia. It's a bit of a thug and will take over any space nearby but it is very bright and cheerful.
