Common Name(s): Bois de Rose

Scientific Name: Dalbergia maritima, Dalbergia louvelii

Distribution: Madagascar

Tree Size: 40-65 ft (12-20 m) tall, 1-2 ft (.3-.6 m) trunk diameter

Average Dried Weight: 58 lbs/ft3 (930 kg/m3)

Specific Gravity (Basic, 12% MC): .74, .93

Janka Hardness: 2,600 lbf (11,570 N)

Modulus of Rupture: No data available

Elastic Modulus: No data available

Crushing Strength: No data available

Shrinkage: Radial: 4.0%, Tangential: 6.7%, Volumetric: 10.8%, T/R Ratio: 1.7

Color/Appearance: Heartwood color is a vibrant magenta or reddish purple, sometimes with darker violet-black streaks. Overall color tends to darken with age to a deep purple to nearly black.

Grain/Texture: Has a fine uniform texture with a very high natural luster.

Endgrain: Diffuse-porous; large pores in no specific arrangement; solitary and radial multiples of 2-3; heartwood deposits (dark red) common; growth rings usually indistinct; rays not visible without lens; parenchyma diffuse-in-aggregates, vasicentric, aliform (winged), and banded (marginal). Heartwood extractives (violet) leachable in water.

Rot Resistance: No data available; being a dense rosewood, it is presumably very durable.

Workability: Bois de Rose is an excellent turning wood. Turns and finishes well, and takes a high natural polish.

Odor: Has a characteristic rosewood scent while being worked.

Allergies/Toxicity: Although severe reactions are quite uncommon, rosewood in the Dalbergia genus, (such as Bois de Rose), has been reported as a sensitizer. Usually most common reactions simply include eye, skin, and respiratory irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: International trade of this species is currently (and rightfully) restricted. National parks and other protected areas within Madagascar have been plundered for their valuable rosewood logs. At present, only residual stockpiles of small turning and carving blanks are available at very high prices.

Sustainability: Bois de Rose is listed on CITES appendix II under the genus-wide restriction on all Dalbergia species—which also includes finished products made of the wood. It is also listed on the IUCN Red List as endangered due to a population reduction of over 50% in the past three generations, caused by a decline in their natural range, and exploitation.

Common Uses: Musical instruments, inlay, fine furniture, carving, turned objects, and other small specialty wood items.

Comments: This sought-after and prized hardwood is only found on the African island of Madagascar. Bois de Rose is french for “rosewood,” and it is in the true rosewood genus (Dalbergia), and could rightly be referred to as Madagascar Rosewood. But to avoid confusion, the common name Madagascar Rosewood belongs to another tree species endemic to Madagascar: Dalbergia baronii.
