Hi garden people, I won a gorgeous peopny in a raffle today but unfortunately it had no ID label or care instructions. It's about 2' high and has two big open flowers (pink) and one unopened bud. I looked on the RHS site and they advised planting in autumn or spring. The pot is not very big for the size of the plant so I don't think it should stay in there until autumn.
Could anyone advise me how and where to plant it to give it the best chance of survival?
I'll get a photo tomorrow if that helps.
