I'd throw it into a corner and ignore it. I bet it would survive, and then invade everywhere. It's a toughie. Phil J

I think you mean a 'Hypericum' , do you? In which case, no mystery about it - they prefer a sunny position, so just dig a hole, and back-fill with a compost and soil mix. Water well!
