Black Cottonwood

Green Giant Poplar - also known as Brooks #6 - is a large, prairie hardy tree ideally suited to shelterbelts. Cold tolerance, drought tolerance, and disease resistance make the green giant a perfect fit for anyone looking for a low maintenance tree. This hybrid poplar variety produces no fuzz.

Named after its white, fluffy seeds with cottony hairs, this hardy tree produces sticky, fragrant buds and has a straight growth habit. Black Cottonwood needs ample moisture and nutrients to grow successfully to full height and are found in the Western provinces and the Yukon with BC being its heartland.
