'Hasse' Southern Magnolia

Magnolia grandiflora (mag-NOL-ee-ah gran-di-FLO-rah)

Family: Magnoliaceae Native Understory (15-40 ft)

'Hasse' is a cultivar of the southern magnolia with a slender canopy in the Magnoliaceae family. Allow plenty of room for its roots that can spread up to four times its canopy width. This extra space will also help the tree to be more drought tolerant. With its wide root spread, it makes a great candidate for a location on a slope. The root system can be a benefit where erosion is an issue, the root system can stabilize or hold the soil, preventing washing. The preferred growing condition include moist, well-drained, acidic, loam based soils. However, less-than-desirable conditions are tolerated. Leaf drop can occur during the first year due to transplant shock. Once acclimated to its site, leaf drop will decrease. Insects, Diseases, and Other Plant Problems: There is some susceptibility to verticillium wilt, as well as magnolia scale. Insect damage from the tulip-poplar weevil and Magnolia borer can be observed. Diseases include blight, scabs, black mildew, and leaf spot.
