Southern Magnolia (Magnolia grandiflora): Iconic Evergreen of the South

Southern Magnolia stands as the quintessential evergreen tree of the American South, celebrated for its massive fragrant flowers, glossy evergreen foliage, and stately presence. Magnolia grandiflora is native to the coastal plains from North Carolina to Texas, where it thrives in the warm, humid climate.

Signature Features

This broadleaf evergreen typically reaches 60-80 feet tall with a pyramidal to rounded crown 30-50 feet wide. The leathery leaves are 5-10 inches long, lustrous dark green above and often rusty-brown and fuzzy beneath. From late spring through summer, the tree produces enormous (8-12 inch diameter), creamy white, cup-shaped flowers with a powerful lemony fragrance that can perfume an entire garden. These are followed by cone-like aggregate fruits revealing bright red seeds on silken threads.

Cultivation and Cultivars

Southern Magnolia prefers full sun to partial shade and rich, moist, well-drained, acidic soil. It's moderately drought-tolerant once established but performs best with consistent moisture. The dense shade and shallow roots make underplanting difficult. Leaf litter is substantial and slow to decompose.

Numerous cultivars offer options for smaller spaces: 'Little Gem' (compact, 20-25 ft, early blooming), 'Teddy Bear' (dense, upright, 20 ft), 'Bracken's Brown Beauty' (cold-hardy, 30-40 ft), 'Edith Bogue' (narrow, cold-hardy), and 'Kay Parris' (small, long bloom season). These extend the tree's usability into smaller residential landscapes and colder zones (to zone 6).
