Very cool. How will you overwinter it? Lift the tubers? Houseplant? I've never grown it myself.

My first time growing it also 'floral'. Ah, so there is a tuber eh? If there is I will attempt to save it that way.

Oh wow. A plant I spotted in the T&M catalog 35 years ago but I've very seldom seen. Supposedly much more common in the UK and other maritime climates, I think Annie's Annuals sold it from time to time. I might have tried at at some point and had no luck with it. It's getting hard enough to remember the plants I do have, much less the ones I tried and failed with. (easily twice as many!)
