Scientific Name: Peltogyne venosa Trade Name: Purpleheart Family Name: Leguminosae

The heartwood is initially dull brown, but it rapidly changes to a bright, vibrant purple. Prolonged exposure darkens the wood to a dark-purplish brown or dark brown, but the original color is easily restored by recutting to expose new wood. Color variation between boards is moderate to high. Presence of minerals in some boards may cause uneven coloration and steaming is reported to affect the color. Peltogyne timbers are reported to vary widely in color between, and probably within species.
