Tzalam — also known as Caribbean Walnut, Mayan Walnut, or False Tamarind — carries a light-to-medium brown heartwood, sometimes touched with reddish or purple hues, in an open, uniform texture with a medium luster and generally straight grain. Some boards resemble Hawaiian koa, and it’s frequently compared to American black walnut for both look and character. It’s a dense, hard wood — durable, resistant to wear, and naturally resistant to rot and decay — which is exactly why it shows up everywhere from fine furniture and cabinetry to flooring, decorative veneer, and door and window frames. That same resistance to weather and humidity makes it just as suitable outdoors, for docks, outdoor furniture, and other exterior applications.
