Bellflower Blooming in my Greenhouse (again!)

Platycodon grandiflorum, to give it its Sunday name. Bought it in supermarket on impulse 'cos I liked the balloons (unopened blooms) two winters ago. Let it get pretty dry (I forgot it) in the greenhouse as winter approached and just put it under a bench. Lo and behold it send up a couple of little shoots in the spring.
They are hardly little bloomers :-)
Also available in blue.
