What's this please ??

Feel I ought to recognise this , but I don't : I feel as if I've never seen it before -- ever !. It's surely some common tree in spring flower.
I found it on a camera prowl walking back from Steve- the- Garage. I've managed to twice scrape the Yaris putting it into the parking here. In my defence I was much heartened when Cal ( a very capable ) driver muttered about difficult parking for elderly folk, as she tried numerous times to get in.
There's lot's of things I find are like that here : tasks I used to find easy are now tedious. Can feel a rant coming so will stop.
