As others have already said it's celandine. Every year it comes up and
covers all the ground below one of my trees where nothing else grows.
It usually comes up about now and stays for a few months. I quite like
it.

I have loads of it and I love it, you don't need to do anything to it as it
just vanishes when it has finished flowering. I don't think horses will eat
it, my old pony often picks at plants in the garden and I have never seen
her touch it.
