I received this a few years ago as a single fan bonus. It has not multiplied much and only had a couple blooms last year for the first time. I'm not sure of the zone equivalent but I'm in southern Ontario off the eastern shore of Lake Huron where our average winter snow cover is about 3-4 feet (except this past winter). It was in an area that was shaded a good portion of the day but I've taken down the tree and will see how it performs in more sun this year.
