Magnolia virginiana (Sweetbay Magnolia)

A genuinely fire-resistant wetland tree able to resprout from root crowns after top-kill, sweetbay magnolia is designated a USDA facultative wetland plant - a fragrant, shimmering-leaved specimen tree equally suited to swampy restoration sites and space-constrained urban plantings.

Species Overview

Magnolia virginiana, or sweetbay magnolia, is a semi-evergreen tree or shrub native to the southeastern U.S. north along the Atlantic coast to New York, often found in wetland areas. It grows 10 to 35 feet tall (occasionally to 50-60 feet in the South), prized for its creamy-white, lemon-scented flowers that bloom in late spring and sporadically throughout summer, with leaves glossy green on top and silvery underneath.

Application

• Wetland and swamp-margin restoration - designated a facultative wetland species
• Specimen and patio tree plantings, including narrow urban corridors
• Fire-resistant plantings - resprouts from root crowns after top-kill
• Wildlife habitat - red seeds attract birds and mammals

Planting Guidance

• Slow-growing with no serious disease or insect problems; prune after blooming during the growing season, as dormant magnolias do not heal easily.
