Hi Hedge,
I have 2 of the Dgrma.Winter Wonderland White Fairy that I divided earlier this year. You may get a spike from yours but who knows. A flower spike will look different. You will see a straight spike come from inside the bottom leaf area. Having new growth shows you are doing something right. FYI mine are outside in east sun (sunscreeded patio) it gets hot here during the day 80's+ and it doesn't mind it.
I'm not sure how cool it got for you but these guys can take 48. I just don't let mine stay in 48 with wind. The wind seems to hurt chids the worst.
I don't know exactly when they like to bloom and mine hasn't yet but I can't wait.
