- Magnolia virginiana: Native to the Eastern and Southeastern United States, including Virginia. It is significantly smaller (typically 10 to 35 feet tall, though taller in Florida) and often grows as a multi-stemmed shrub or small tree.
- Magnolia officinalis: Features large, fragrant white flowers that are 10–15 cm wide with 9 to 12 thick tepals.
- Magnolia virginiana: Features smaller, cup-shaped flowers about 5–8 cm wide, emitting a strong, lemony-vanilla fragrance.
