African Walnut is derived from the Lovoa Trichilioides tree -- a monoecious, evergreen that is indigenous to Central and Southern Africa's tropical regions. Its heartwood color can vary anywhere from a golden brown to a reddish brown, often with darker streaks and/or portions. Over time, its color will darken to deeper brown tones. The sapwood is narrow, grey to beige in color, and clearly demarcated from the heartwood. Despite it not being a true walnut (of the Juglans genus), it shares many of the basic characteristics.
