Answer: Saucer Magnolia (Magnolia soulangeana) is a lovely tree ultimately about 30 feet high and wide and fairly adaptable as long as the soil is good. According to Michael Dirr's "Manual of Woody Plants", it is hardy into Zone 4 and prefers a moist, deep, organic soil with a pH between 5.0 and 6.5 in sun or light shade. If your conditions are windy, or baking hot during the summer, or very wet for instance, the tree might not survive. As with any tree selection, it is a judgement call.
