Noteworthy Characteristics

Magnolia virginiana, commonly called sweet bay magnolia, is native to the southeastern United States north along the Atlantic coast to New York. In the northern part of its cultivated growing range, it typically grows as either a 15-20' tall tree with a spreading, rounded crown or as a shorter, suckering, open, multi-stemmed shrub. In the far southern United States, it is apt to be more tree-like, sometimes growing to 60' tall. Features cup-shaped, sweetly fragrant (lemony), 9-12 petaled, creamy white, waxy flowers (2-3" diameter) which appear in mid-spring and sometimes continue sporadically throughout the summer. Oblong-lanceolate shiny green foliage is silvery beneath. Foliage is evergreen to semi-evergreen in warmer climates and semi-evergreen to fully deciduous in colder climates. Cone-like fruits with bright red seeds mature in fall and can be showy.

Genus name honors Pierre Magnol, French botanist (1638-1715).

Specific epithet means of Virginia.

‘Jim Wilson’, commonly sold as MOONGLOW, is a patented cultivar that is distinguished from the species by (1) more vigorous upright growth, (2) better cold hardiness with semi-evergreen foliage in the northern part of its range, and (3) slightly larger flowers. This is a medium-sized tree with an oval to vase-shaped form. It typically grows over time to 35’ tall with a spread of 18’. Cup-shaped, sweetly fragrant (lemony), 9-12 petaled, creamy white, waxy flowers (2-3” diameter) appear in mid-spring (May-June) for about one month and sometimes continue sporadically in the summer. Semi-evergreen elliptic to lanceolate leaves are glossy dark green above and silvery-green below. Cone-like fruits with bright red seeds mature in fall and can be showy. U.S. Plant Patent PP12,065 was issued on August 28, 2001.


No serious insect or disease problems. Susceptible to chlorosis in alkaline soils.


Excellent specimen tree for lawns or tall multi-stemmed shrub for shrub borders. Use in foundation plantings, near patios or on the periphery of woodland areas. Often planted in parks. Will grow in wet soils such as those found in low spots or near ponds/streams.
