Comments: This lovely open growing tree produces a profusion of lightly fragrant narrow petaled flowers in early spring. As the tree matures the flowering increases to a point where it looks like a billowy white cloud in flower. The roots are not aggressive and this tree casts open shade making it possible to garden under the canopy.
Best grown in moist, organically rich, well-drained loams in full sun to part shade. Among magnolias, this species is one of the earliest to bloom in spring.
