Acacia Koa; Native Hawaiian Plant
Koa trees thrive between the elevations of 330–550 feet anywhere between 33–197 inches of rainfall annual.
Koa is one of the fastest-growing trees in Hawaii. In areas with deep rich volcanic ash koa trees are capable of growing up to 20–30 ft in a five year span. A typical tree can reach heights nearly a 100 feet high.
The wood of koa trees are one of the most sought-after in the world. With the demand, it can be one of the priciest. The solid density and reddish tint wood is very similar in strength and weight to the Black Walnut wood. The trunk of koa trees were used by ancient Hawaiians to build wa’a (dugout outrigger canoes) and papa he’e nalu (surfboards).
Koa is also a tonewood, often used in the construction of ukuleles, acoustic guitars, Weissenborn-style Hawaiian steel guitars, electric guitars as well as drum and percussion instruments.
Possessing skills of a woodman, koa wood also makes for beautiful furniture, cabinetry, flooring, framing, countless other household and unique uses.
