Here in southern UK Leucojum roseum is an easy bulb for unheated greenhouse culture, flowering anytime from mid August onwards, a succession of flowers over a couple of months. It has survived (only just!) in a sandy raised bed outside but has not flowered there. Under glass it sets seed readily and this is a good means of increase. The green capsules ripen quickly ..... and it pops up in the plunge and surrounding pots if you don't catch it in time! Tony Goode. Norwich UK. Mintemp -8C
