Color/Appearance: Very wide sapwood is a creamy white to grayish color. Comparatively narrow heartwood color ranges from a medium to dark brown, sometimes with green, purple or black streaks.
Grain/Texture: Grain is straight, with a medium to fine uniform texture. Moderate natural luster.
Endgrain: Diffuse-porous; small to medium pores in no specific arrangement, numerous; solitary and in radial multiples of 4 or more; growth rings distinct; narrow rays visible without lens, normal spacing; parenchyma marginal.
Rot Resistance: Rated as non-durable to perishable regarding decay resistance, and also susceptible to insect attack.
Workability: Generally easy to work with both hand and machine tools. Turns, glues, stains, and finishes well.
Odor: No characteristic odor.
Allergies/Toxicity: Although severe reactions are quite uncommon, species in the Magnolia genus have been reported to cause asthma-like symptoms and runny nose. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Readily available within its natural range, though difficult to find elsewhere. Prices should be low for a domestic hardwood.
Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.
Common Uses: Veneer, plywood, interior trim, upholstered furniture frames, and general utility wood.
Comments: Southern Magnolia is the hardest and heaviest of the three primary magnolia species that are commercially harvested in the United States.
Scans/Pictures: A special thanks to Mike Leigher for providing the wood sample of this wood species.
