Eucalyptus grandis · Hardwood
AI-generated identification · may be incorrect- Type
- Hardwood
- Origin
- Native to Australia; extensively grown in plantations across South Africa, South America, and India.
- Hardness
- 1,100 lbf (Medium - Janka rating can vary between 700-1400 depending on subspecies)
- Durability
- Moderately Durable; heartwood has some resistance to rot, though sapwood is susceptible to Lyctid borer attack and decay in wet conditions.

Grain Pattern
Generally straight to slightly interlocked with a medium to coarse texture; visible irregular growth rings and some spalting or fungal staining in the heartwood transition.
Color & Appearance
Sapwood is pale yellow to white; heartwood ranges from pinkish-red to light brown. Exhibits low luster and is prone to darkening with age/UV exposure. Blue/gray fungal staining is visible in the cross-section.
Hardness (Janka)
1,100 lbf (Medium - Janka rating can vary between 700-1400 depending on subspecies)
Durability & Decay Resistance
Moderately Durable; heartwood has some resistance to rot, though sapwood is susceptible to Lyctid borer attack and decay in wet conditions.
Value & Age
0.80 - 2.50 USD per board foot depending on grade and region; often sold as lower-cost utility timber.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Young growth, likely 5-10 years based on the small diameter and rapid growth ring spacing typical of plantation eucalyptus.
Common Uses
General construction, utility poles, flooring, furniture, pallets, pulpwood for paper, and firewood.
Geographic Origin
Native to Australia; extensively grown in plantations across South Africa, South America, and India.
Workability
Fair to good; however, prone to significant warping and splitting during drying (checking). Can be abrasive on tools due to high density in some hybrids.
Finish Recommendations
High-solids oils or penetrating sealers to mitigate cracking; takes paint and film-finishes well once properly seasoned and stabilized.
Notable Features
Distinctive pungent or medicinal scent when freshly cut; high moisture content leads to rapid checking/cracking on the end grain as shown in the photo.
