Biggest leaves, tallest tree, but not as prolific of a bloomer. Out of all the magnolias, the D.D. Blanchard is one of the largest varieties, producing dark green, large leaves with a rusty brown underside. It can reach a maturity height of 75 ft. to 80 ft. with a canopy of 35 ft. to 40 ft. W, making an excellent shade tree. It is capable of maintain a straight, central trunk, which allows it to be grown full to the ground or be pruned into tree form with a visible trunk. Flowers bloom in late spring, with sparse but continued flowering throughout the summer. The fragrant blossoms are large (can be 8 in. W) and are cup-shaped in appearance. USDA Zones: Zone 7, Zone 8, Zone 9.
