Growing notes
- Plant as a specimen tree or against a tall wall — the standard evergreen magnolia of warm-temperate gardens worldwide, eventually 15 m or more
- Lemon-scented enormous flowers in summer — most powerfully fragrant in the evening
- Distinct from the deciduous magnolias already in the database (Magnolia × soulangeana, M. officinalis bark) — Magnolia grandiflora is evergreen and summer-flowering
- Compact cultivars (‘Little Gem’, ‘Bracken’s Brown Beauty’) suit smaller gardens
