I grew my plants outside last year, and this year I brought my plants in as soon as the night time temperatures get close to freezing, and I put them on my south facing window. *I didn't cut off any leaves, nor putting them in the fridge. *I live in North Jersey and I keep my house rather chilly, so they seem to fall into dormancy (small rosettes, slow to no growth) and come back out naturally. *I inspected them today and I can see the beginnings of some flower scapes poking up. *More seeds this year!
