It's only just about frost hardy, and a light frost at that - more info in the link below as to how to grow

You may glean from the information that its usual to buy and plant in spring, not sure it can be kept till next spring, you might have to try growing it in a pot indoors.

I have a friend in Hove who grows this on an enclosed balcony (sliding glass doors open in summer - becomes a conservatory in winter) - they bought it after seeing it growing in one of the glass houses at Kew Gardens.

I have a bulb of this that I got last year. What information I found was that it needs to be planted about 6" deep. Also it can be reluctant to grow, and the first shoots are very delicate. Mine hasn't put in an appearance, yet, but my winter growing bulbs are finally starting to come up. It likes sun and temperatures in the low 60's and down into the 50's. It was a bit of a disappointment last year, but I am hoping for better this year.
