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 75-80 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.

Most Plant Me Green trees can be shipped and planted any time of year, unless the variety is specified as only seasonal delivery (such as bare root trees). Our shipping schedule is Monday, Tuesday, and Wednesday. This is to ensure our trees do not stay in a box longer than necessary and arrive to you as healthy as possible. If a package needs to arrive prior to a specific date, or at a more convenient time for you, please notate that upon placement of your order. On some occasions, severe weather and other unusual issues can delay shipping and delivery of your Plant Me Green package. Holiday shipping schedules are set by the carriers.
First, decide on a planting location. Consider carefully what kind of sun, soil, and growing-space your tree or shrub will need. Once you've located the perfect spot, the hole you are digging must be at least double the width and as deep as the root system you are planting. The top of the root system should be level with the ground. Before placing the tree or shrub in the hole, use your hands to gently break up the root system. Once the tree is in place, backfill the hole with native soil and any leftover potting material. Pack down the soil to eliminate any air pockets. When finished, water thoroughly. To insure your plants a successful growth rate and productive life, plant your seedlings per the instructions included in your PlantMeGreen package.
Plant in well-drained, acidic soil in an area that receives full sun to partial shade. It is generally intolerant of soil extremes (dry or wet). It is also intolerant of many urban pollutants. Make sure the tree has plenty of room to grow to its full size. Mulch creating a 3-4 inch layer at base but leave room at the trunk of the tree. Water regularly for the first few years until your magnolia is established. Magnolias need 40-80 inches of water every year. Prune as needed in winter. They are not particular prone to insects or diseases.

Beautiful Tree, Full size of listing

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.

Thank you for calling this to our attention Karen. The product description has been updated to state the correct hardiness zones.

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.
