Southern Magnolia
Magnolia grandiflora
Also known as: Evergreen Magnolia, Bull Bay, Large-flowered Magnolia
Southern Magnolia is a fine-textured hardwood from the southeastern United States, recognised as much for its iconic white flowers as for its pale, even-grained timber. Commercially underutilised relative to its qualities, it machines to an exceptionally smooth surface and is favoured for furniture, turning, and applications requiring fine detail work.
Botanical Profile
Magnolia grandiflora is a large evergreen tree of the Magnoliaceae family, native to the coastal plain of the southeastern United States from North Carolina to Texas. It reaches 20–30 metres with a broad, dense crown. The flowers — up to 30 cm across — are among the largest of any native North American tree.
Physical Properties
Diffuse-porous hardwood with fine, uniform texture and air-dried density of approximately 575 kg/m³. Janka hardness of 1,020 lbf places it comparable to Black Walnut. Straight grain machines cleanly. Tangential shrinkage 6.6%, radial 5.4% — moderate and relatively balanced.
Workshop Notes
Blunting Effect
Low — works cleanly with sharp tools
Gluing Advice
Good with standard woodworking adhesives
Finishing
Excellent — takes stains and clear finishes evenly due to uniform texture
Steam Bending
Moderate steam bending capability
Historical Context
Magnolia timber was used by early American settlers for furniture and interior millwork, particularly in the Gulf Coast states. It appears in historic antebellum plantation homes throughout Louisiana and Mississippi. Its commercial use declined as more abundant species dominated the lumber trade, but craftsmen continue to prize it for specialty work.
