I found this easy to grow in a good mix of gritty 'river soil' with lots of leafy compost. I kept it in a large terracotta pot in a cold greenhouse which receives morning sun then midday shade. I repotted it in spring 2010 into the same pot, giving it some fresh compost being careful not to disturb the already growing roots but it had sunk in the pot so I placed more compost below and above the bulb. It survived a very cold winter 2009/10 but the following winter with 7 weeks below freezing killed it even though it was kept quite dry.
