Description
A purplish hardwood obtained from species in the genus Peltogyne that are native to tropical regions of Central and South America. Purpleheart or amaranth, wood has a fine, uniform texture and grain that is straight or slightly roey. The durable, shock-resistant wood is sometimes used for carving and for vehicle construction.
Synonyms and Related Terms
Peltogyne; amaranth (wood); violet wood; amarante (Fr.); amaranto (Esp.) ; pau roxo (Port.)
Physical and Chemical Properties
- Tree grows to heights of 50 m and diameter of 1 m.
- Specific gravity = 0.8-1.0 (air dry)
- Density = 60-65 ppcf
- Heartwood is dull purplish brown when cut but with exposure to air turns a deep eggplant purple; with further aging it becomes dark brown
- Grain is usually straight and texture is medium with a good natural luster
- Wood is very resistant to decay and insect attack
Additional Images

Working Properties
- If wood is heated with dull tools, or if cutter speeds are too high, purpleheart will exude a gummy resin that can clog tools and complicate the machining process
