Selfie — or rather "Self Sown"!

Could anyone tell me what this is please?

About 2'6"" and in flower now. Self sow and appeared in a rockery amongst hyacinths and crocus and nearly treated as a weed.

Pleased i waited as it would make a welcome addition to the spring garden in the right place.

A green/yellow flower.

Try asking on a gardening forum.

I checked with my expert (botanist wife) and you have photographed a euphorbia cyparissias.

Thanks - I shall get my wrist slapped next time I see my son's partner - She got RHS Gold at Sandringham Show!

Looks to me to be what we call leafy spurge. It's a noxious weed (not sure of the status in England) that is really difficult to get rid of. It's quite voracious and will take over quickly.
