Coral or Craters?

This was going to be my blip yesterday, but the Moon Flower won out.

Again, I have no idea what this flower is called? Where is my brother when you need him? Just because I have a semi-famous dad doesn't mean I am any good at plant ID. Mind you, if a duck landed on the allotment, he would have no idea if it was a Pochard or a Grebe, so each to their own eh!

This flower grows next to the one I blipped yesterday. It sort of carries on the planetary theme, as I think the flowers look very crater like. Or may be it reminds me of a coral?

Either way, the colours on it are quite amazing.
