Here in the UK I have a couple pf pots of this plant, inside an unheated, but sheltered greenhouse, and one pot flowered all through the winter. Each bulb has 1 stem but this branches so many flowers, in this case over several months. The flowers stem would have been frosted several times and the pot too last winter, though probably rarely more than 5 degrees (C) of frost. I was intreaged by the "corm" when I unpotted one as I had a vertical heart shaped cluster, about 1" (2.5cms) diameter/tall with several growing points, that seemed reluctant to separate, so got repotted as 1.
