Hypericum 'Hidcote'

Does anyone know what this is please? #plantid It's just sprung up in my hedge! It's quite pretty but not sure if I should yank it out!!

It's Hypericum (St Johns Wort) it does self seed 👍👍

Thank you so much @greengrub 🙏🏼 Is it a weed?

If it's at low level, it's hypericum 'calycinum', which I plant as ground cover. Highly effective. However, my definition of a weed is 'a plant in the wrong place'. If you like it there, and it will spread, that's fine. If you don't like it there, get rid

I like it haven't got a clue what it is.i would leave it and see what happens
