A good plant if a shrub is what your looking for. Has nice autumn colour, as well as a rich green colour throughout spring and summer. However is does not give off any shade, or have any value along property lines. Betula nana could only serve close to a house or building as ground cover. It can grow in areas that have very cold winters so it is a tough plant that will survive the winters in Southern Ontario easily.
