Foxgloves - do I leave out for winter?
Today I noticed new growth on one of my "Foxy" Foxgloves, it looks as green as a summer day, even during this 28 degree weather. I also discovered 9 growing in my garden a couple of weeks ago so for the sake of saving them, I dug them up and put them in individual plant containers and put them up on the window sill, but I've been told that they need to be left out through the winter in order for them to flower next year. I know it's a bienniel but now I'm second guessing bringing them indoors, did I screw up their evolution? Please help!
