Wisconsin is a snowy area of the country that has bitter cold winters. In addition to this, the summers are hot in this part of the country, so some plants may have trouble adjusting to the extreme temperatures.
When my sister moved to this area of the country, we had a hard time finding perennials that we could grow that would survive the cold winter without dying. Even when you brought some of the plants inside, they never seemed to do well when it started to get chilly. After a bit of research, these are some of the plants that did the best in Wisconsin.

Bleeding hearts have blooms that are red, white, or pink, and they dangle from the plant in the shape of a heart. These plants will grow well in zones three to nine, and they can vary in height.
