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 deep South, 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 the South, but generally deciduous in the St. Louis area. Cone-like fruits with bright red seeds mature in fall and can be showy. See also Magnolia virginiana var. australis which primarily differs from the species by being somewhat taller, having more fragrant flowers and being more likely to be evergreen.
No serious insect or disease problems. Susceptible to chlorosis in alkaline soils. Not reliably winter hardy in the St. Louis area.
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.
