Is Zebrawood a Hardwood: Botanical Classification
Zebrawood's hardwood classification begins with its botanical identity within the Microberlinia genus. This African species belongs to the Fabaceae family (legumes), producing trees that can reach heights of 130 feet with trunk diameters exceeding 5 feet. The scientific classification places zebrawood firmly in the deciduous tree category, which forms the fundamental basis for hardwood designation.
The hardwood versus softwood classification system relies on botanical characteristics rather than actual wood hardness. Hardwood trees are angiosperms (flowering plants) with broad leaves that typically shed annually, while softwoods come from gymnosperms (conifers) with needle-like leaves. As our comprehensive wood selection guide explains, this botanical distinction fundamentally determines wood classification regardless of physical properties.
Zebrawood Scientific Classification
- Kingdom: Plantae (plants)
- Family: Fabaceae (legume family)
- Genus: Microberlinia (two recognized species)
- Primary Species: M. brazzavillensis (most common commercial variety)
