Hairy Purpleheart
Scientific name: Peltogyne pubescens
Overview
Hairy Purpleheart is a rare tropical hardwood native to the Amazon Basin of northern South America, occurring primarily in Brazil and parts of the Guiana Shield. A member of the Fabaceae family, it belongs to the Peltogyne genus, a remarkable group of hardwoods renowned for their brilliant purple heartwood and exceptional durability. The species name pubescens, meaning “hairy” or “covered with fine hairs,” refers to the fine hairs found on young twigs, leaves, or other botanical structures, an identifying characteristic used by botanists.
Like all Purpleheart species, Hairy Purpleheart undergoes one of the most dramatic color transformations found in any hardwood. Freshly cut heartwood begins as a grayish-brown or olive-brown before oxidizing into vibrant violet and deep purple after exposure to air. Combined with excellent mechanical properties and outstanding decay resistance, it is highly valued for decorative woodworking, although it is rarely identified separately within the commercial lumber trade.
Quick Facts
- Common Name: Hairy Purpleheart
- Scientific Name: Peltogyne pubescens
- Region: South American Hardwoods
- Tree Size: 60–100 ft (18–30 m) tall, 2–3 ft (0.6–0.9 m) trunk diameter
- Average Dried Weight: Approximately 57 lbs/ft³ (915 kg/m³)
- Janka Hardness: Approximately 2,520 lbf
- Grain: Straight to slightly interlocked
- Texture: Fine to medium
Identification Characteristics
Freshly cut heartwood appears grayish-brown to olive-brown before rapidly developing its characteristic violet and deep purple coloration through oxidation. With prolonged exposure to ultraviolet light, the vivid purple gradually darkens to a rich brownish-purple. The sapwood remains pale cream to yellowish-white and is sharply defined from the heartwood. Grain is generally straight but may occasionally display slight interlocking, while the texture is fine to medium with a moderate natural luster.
Key identification traits include:
- Fresh heartwood initially grayish-brown
- Oxidizes into vivid violet and deep purple
- Pale cream to yellowish-white sapwood
- Straight to slightly interlocked grain
- Fine to medium texture
- Moderate natural luster
- Excellent natural durability
Working Properties
Hairy Purpleheart works much like other members of the Peltogyne genus. Its density requires sharp carbide tooling to achieve the best machining results. Slightly interlocked grain may occasionally produce tear-out during planing, while turning, sanding, and polishing produce an exceptionally smooth surface. Finishes containing ultraviolet inhibitors help slow the natural darkening of the famous purple heartwood.
- Machines well with carbide tooling
- Moderately difficult due to density
- Interlocked grain may produce minor tear-out
- Turns exceptionally well
- Excellent polishing characteristics
- Glues well with proper preparation
- Produces a smooth, lustrous finish
Safety Note
Wood dust may cause skin, eye, or respiratory irritation in sensitive individuals. Repeated exposure may occasionally result in mild allergic skin reactions. Proper dust collection, respiratory protection, and eye protection should always be used when machining or sanding this species.
Common Uses
Hairy Purpleheart combines exceptional durability, impressive strength, and striking coloration, making it suitable for numerous premium woodworking applications, including:
- Fine furniture
- Cabinetry
- Architectural millwork
- Flooring
- Decorative veneers
- Turned objects
- Knife handles
- Musical instruments
- Inlays
- Collector wood specimens
Sustainability & Notes
Hairy Purpleheart grows within the Amazon rainforest, where responsible forest management plays a critical role in preserving biodiversity and protecting native hardwood resources. Like most members of the Peltogyne genus, it is rarely harvested or marketed separately from other Purpleheart species.
Commercial lumber specifically identified as Peltogyne pubescens is uncommon, making authenticated specimens particularly valuable for botanical collections, research, and educational reference.

Collector Notes
Hairy Purpleheart is an outstanding addition to a documented Peltogyne collection because authenticated specimens are seldom encountered in commercial lumber markets. Recording the scientific name, collection locality, supplier, and acquisition date helps preserve the specimen’s scientific and historical value. Displaying this species alongside Purpleheart, Slender-Stem Purpleheart, Paradox Purpleheart, Sessile Purpleheart, Few-Flowered Purpleheart, Maranhão Purpleheart, Lecointe’s Purpleheart, Dense-Flowered Purpleheart, Recife Purpleheart, and Mexican Purpleheart showcases the impressive diversity found within one of the world’s most recognizable hardwood genera.
