Identify the Flower - please?

I'm counting to see how long it takes before a blipper identifies this flower correctly.
That's because I'm ashamed to say that I haven't a clue what it is called, although it's right outside our back door.
Busy, busy day today, and it will be even busier tomorrow, so I apologise in advance for lack of comments.
I was so taken with moaning about my sore knee (which is now heaps better, but I'm being cautious) that I forgot to say on Sunday that it was our younger grandson's third birthday, so we sang him a Skyped Happy Birthday. Time flies..................We've only ever seen either of them on one birthday, and that was the elder one's first. and we went to Taiwan to see them for the occasion.
