I was given one of these plants, which is in a large pot, yesterday. I've not grown them before and would welcome any advice. Please note that it will be kept outside on the allotment as I've nowhere else for it.
It needs a sandy, well-draining soil in a south-facing position; in colder areas it will need some winter protection. It's a bulb which produces leaves in spring, then dies down for summer and flowers in September-October.
