Common Name(s): Mulberry
Scientific Name: Morus spp. (Morus alba, M. nigra, M. rubra, etc.)
Distribution: Red Mulberry is native to Southeastern United States, other species are found worldwide
Tree Size: 30-50 ft (10-15 m) tall, 1-1.5 ft (.3-.5 m) trunk diameter
Average Dried Weight: 43 lbs/ft3 (690 kg/m3)
Specific Gravity (Basic, 12% MC): .55, .69
Janka Hardness: 1,680 lbf (7,470 N)
Modulus of Rupture: 11,680 lbf/in2 (80.6 MPa)
Elastic Modulus: 1,352,000 lbf/in2 (9.32 GPa)
Crushing Strength: 6,990 lbf/in2 (48.2 MPa)
Shrinkage: Radial: 3.3%, Tangential: 6.6%, Volumetric: 10.3%, T/R Ratio: 2.0
Grain/Texture: Grain is straight, with a uniform medium texture. Good natural luster.
Endgrain: Ring-porous; large earlywood pores 2-5 rows wide, small latewood pores in clusters and tangential bands; tyloses and other gum deposits common; parenchyma vasicentric, aliform, and confluent; medium to wide rays, spacing normal.
Rot Resistance: Rated as very durable, with good insect resistance and weathering properties.
Workability: Responds well to both hand and machine tools. Turns, glues, and finishes well.
Odor: No characteristic odor.
Pricing/Availability: Due to its small size and scattered distribution, Mulberry is seldom if ever harvested commercially for lumber. Smaller pieces are sometimes available locally throughout the tree’s natural range. Expect prices to be high 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: Fence posts, furniture, and turned objects.
Comments: Mulberry is perhaps better known for its fruit; the tree’s leaves are also the sole food source for the silkworm, which is used to produce silk.
The wood itself looks very similar to Osage Orange, though Mulberry tends to be significantly lighter.
