This is one of my favorite plants because they are so easy to grow, and the flowers are so cheerful and bright. I have to fence my entire garden from deer, rabbits and woodchucks that want to eat everything; so I like to grow vines on the fences. I'm so fond of these vines that for an experiment I dug one up and potted it the day when our first frost was predicted in September, and also clipped some shoots for cuttings. They kept on growing without a pause, in my sunny south porch windows and have continued to climb and bloom all winter long. It is now February and they are still going strong. They will climb any string hung for them. I live where we have Zone 4 winters and a short growing season so any plant that blooms all winter is very welcome. Some plants overwintered inside quit blooming in winter but this plant keeps right on going. I think they will be inside every winter from now on. I do use some supplemental fluorescent lights for my plants in winter because the days are so short here and sunshine is rare. The room is cool at night in the 50s F.
