This canopy tree is the hardiest of the native, tree-sized magnolias (and the only magnolia that is native to Canada). Large, round-topped deciduous tree and one of the few magnolias that can serve as a shade tree. Needs a large space but is an excellent tree for the large property. Flowers not showy, greenish and only 2 inches across.   May take 12 or more years for first flowers to appear. Cucumber-like fruit is often missed because they occur at the top of the tree. Often produces respectable fall color. Occurs naturally on cool, moist sites, mostly in the mountains. Any home planting needs to imitate a similar situation. Soil must be moist, deep and well drained. Does not withstand extreme drought, wetness or pollution. Cultivars available.

Many fruits fall to ground with seeds still contained and are popular food for ground-feeding birds and small mammals
