Pau Rosa
Scientific name: Swartzia fistuloides
Overview
Pau Rosa is a dense and durable tropical hardwood native to the rainforests of Central and West Africa. Although it is not widely known outside specialty hardwood markets, the species is valued for its strength, attractive reddish-brown heartwood, and excellent wear resistance. Its combination of density, stability, and fine finishing qualities makes it suitable for furniture, flooring, cabinetry, heavy construction, and decorative woodworking. As one of the lesser-known members of the Swartzia genus, Pau Rosa is also an appealing species for collectors of exotic hardwoods.
Quick Facts
- Common Name: Pau Rosa
- Scientific Name: Swartzia fistuloides
- Region: African Hardwoods (West & Central Africa)
- Tree Size: 80–130 ft tall, 2–4 ft trunk diameter
- Average Dried Weight: Approximately 58 lbs/ft³ (930 kg/m³)
- Janka Hardness: Approximately 2,500 lbf
- Color: Reddish brown to dark brown
- Grain: Straight to slightly interlocked
- Texture: Fine to medium
Identification Characteristics
Pau Rosa develops a rich reddish-brown heartwood that gradually darkens with age to a deeper brown. The grain is usually straight but may occasionally display mild interlocking, while the fine to medium texture produces smooth finished surfaces with a subtle natural luster. Its high density and impressive hardness distinguish it from many other African hardwoods.
Key identification traits include:
- Reddish-brown to dark brown heartwood
- Fine to medium texture
- Straight to slightly interlocked grain
- Moderate natural luster
- Dense and highly durable wood
Working Properties
Pau Rosa can be somewhat challenging to machine because of its density, but sharp cutting tools generally produce excellent results. The wood turns exceptionally well, sands smoothly, and accepts oils and clear finishes that enhance its rich natural color.
- Machines well with sharp tools
- Turns exceptionally well
- Produces a smooth finished surface
- Excellent wear resistance
- Accepts oils and clear finishes beautifully
Safety Note
Wood dust may cause skin, eye, or respiratory irritation in sensitive individuals. Appropriate dust collection and respiratory protection are recommended during machining.
Common Uses
Thanks to its exceptional strength, durability, and attractive appearance, Pau Rosa is used in a variety of demanding woodworking and construction applications, including:
- Furniture
- Cabinetry
- Flooring
- Heavy construction
- Interior joinery
- Woodturning
- Decorative millwork
- Specialty woodworking projects
Sustainability & Notes
Pau Rosa is harvested throughout portions of West and Central Africa, primarily for regional use. While it is not among Africa’s major commercial export timbers, responsible forest management remains important to preserve tropical forest ecosystems and ensure the sustainable use of this durable hardwood.

Collector Notes
Pau Rosa is an excellent collector species because it represents one of the lesser-known members of the Swartzia genus found in Africa. Its impressive density, rich reddish-brown coloration, and limited availability outside its native range make it a distinctive addition to exotic hardwood collections. A well-documented sample showcases the remarkable diversity of African hardwoods beyond the continent’s better-known commercial timber species.
