A Note About Trees and Shrubs that remain Hearty in Michigan Growing Zones.
Michigan Tree Climate:
Michigan has two peninsulas: the Lower Peninsula and the Upper Peninsula. The Lower Peninsula has typically milder seasons, with hot summers and cold winters. The northern portion of the Lower Peninsula and the Upper Peninsula have more extreme weather, typified by heavy snow, freezing temperatures, and shorter summers. These cold winters often linger below zero for days, with the record set at -51°F. Although the summers are usually in the mid-80s, temperatures in the southern regions of the Lower Peninsula can get quite hot, with the record high set at 112°F in 1936.
In Michigan, our hardiness zones range from 4a in the western Upper Peninsula and northern Lower Peninsula to 6b in the southeast and along the Lake Michigan lakeshore. East Lansing, Michigan is in zone 5b (-10 to -15 F)
