Magnolia - D. D. Blanchard (Southern)
Best Planted in USDA Hardiness Zone: 7-9.
Plant Quick Guide
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 75-80 feet with a canopy of 35-40 feet in width, 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 width) and are cup-shaped in appearance. USDA Zones: Zone 7, Zone 8, Zone 9.
Note: At best, Magnolia grandiflora is considered to be winter hardy to USDA Zone 6b. If grown in Zone 6b, it should be sited in a protected location. Plants may become somewhat deciduous in hard winters.
Our tree arrived very healthy and beautiful. It was at the top of the size range listed (might have been slightly bigger). We planted it in two days and so far so good, it looks perfect.
Southern Magnolia- D. D. Blanchard
There is obviously a misprint in the zoning of this tree. Zone 5 has a range down to negative 20 degrees. This tree can only take arrange down to 5 degrees.
I got so excited seeing this tree in the zone as I'm from the south and thought perhaps this is some type of hybrid. I love magnolia trees but I'm unable to grow them here in zone 5. Purchasers just be aware.
I am I NE Wisconsin, supposedly Zone 5. We have winters where it is below 0 F degrees many days. Caution on your tree choice and zone.
