Scientific Name: Eucalyptus grandis

Distribution: Eastern Australia; also grown on plantations worldwide

Tree Size: 100-165 ft (30-50 m) tall, 4-7 ft (1.2-2 m) trunk diameter

Average Dried Weight: 40 lbs/ft3 (640 kg/m3)

Specific Gravity (Basic, 12% MC): .48, .64

Janka Hardness: 1,260 lbf (5,600 N)

Modulus of Rupture: 15,640 lbf/in2 (107.8 MPa)

Elastic Modulus: 2,052,000 lbf/in2 (14.15 GPa)

Crushing Strength: 8,020 lbf/in2 (55.3 MPa)

Shrinkage: Radial: 5.9%, Tangential: 10.1%, Volumetric: 15.5%, T/R Ratio: 1.7

Color/Appearance: Heartwood color ranges from pink to reddish brown. Paler sapwood is sometimes indistinct from heartwood.

Grain/Texture: Usually straight-grained or shallowly interlocked, with a uniform medium to coarse texture.

Endgrain: Diffuse-porous; exclusively solitary; large to very large pores in no specific arrangement, few to very few; tyloses present; parenchyma vasicentric, confluent; narrow rays, spacing fairly close.

Rot Resistance: Rated as durable to very durable; poor insect resistance.

Workability: Fairly easy to work with both hand and machine tools, though Rose Gum experiences a large amount of shrinkage when drying, and a relatively large amount of movement in service. Glues, stains, and finishes well.

Odor: No characteristic odor.

Allergies/Toxicity: Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with Rose Gum, though several other species within the Eucalyptus genus have been reported to cause various allergic reactions. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Occasionally exported to North America. Available in good sizes and lengths in board form. Prices are moderate for an imported hardwood.

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.

Common Uses: Flooring, millwork, furniture, and boatbuilding.

Comments: Rose Gum is a common plantation species, though a hybrid species marketed as Lyptus® is grown in Brazil: Rose Gum is bred with an Indonesian species (Eucalyptus urophylla) to help increase disease and insect resistance.
