How Hardy are Magnolia Trees?
Hardiness of magnolia trees varies widely depending on the species. For example, Champaca magnolia (Magnolia champaca) thrives in humid tropical and subtropical climates of USDA zone 10 and above. Southern magnolia (Magnolia grandiflora) is a slightly tougher species that tolerates relatively mild climates of zone 7 through 9. Both are evergreen trees. Hardy zone 6 magnolia trees include Star magnolia (Magnolia stellata), which grows in USDA zone 4 through 8, and Sweetbay magnolia (Magnolia virginiana), which grows in zones 5 through 10. Cucumber tree (Magnolia acuminata) is an extremely tough tree that tolerates extreme cold winters of zone 3. The hardiness of Saucer magnolia (Magnolia x soulangiana) depends on the cultivar; some grow in zones 5 through 9, while others tolerate climates as far north as zone 4. Generally, hardy magnolia varieties are deciduous.
