Grain Pattern
Straight to wavy, fine even texture; typically features narrow, very distinct growth rings that create a subtle ring-porous or semi-ring-porous cathedral figure on flat surfaces.

Approximately 1,600 lbf (Hard); comparable to White Oak or Hickory.
Durability & Decay Resistance
Durable to Very Durable; heartwood is highly resistant to rot and insect attack, suitable for outdoor use though rarely available in large dimensions.
Value & Sustainability
- Estimated Market Value
- $40.00 - $60.00 per board foot; typically sold as small turning blanks or logs rather than dimensional lumber due to tree size.
- Wood Age Estimate
- The sample appears recently cut or sanded, evidenced by the sharp edges and light surface color, though the tree itself likely was 20-40 years old based on ring curvature.
- Sustainability Status
- Not listed on CITES or IUCN Red List; generally considered sustainable but available in limited quantities as it is an ornamental tree.
Common Uses
Turning, archery bows, tool handles, fine furniture inlay, musical instruments (bagpipes, recorders), cabinetry, and jewelry boxes.
Geographic Origin
Central and Southern Europe; naturalized in North America and other temperate regions.
Workability
Excellent with hand and machine tools; turns beautifully and takes a very smooth finish. However, its high density requires sharp tools to avoid burning.
Finish Recommendations
High-gloss finishes such as shellac or lacquer highlight its natural luster; clear oils (linseed or tung) deepen the rich brown of the heartwood.
Notable Features
Highly toxic; all parts of the tree contain cytisine. Woodworkers should wear respiratory protection as dust can cause nausea or illness. It is historically known as 'False Ebony'.
