Notes: Koa are fast growing trees, especially when young, and can reach impressive heights in upper elevations. In Hawaiian, koa means "brave, bold, and fearless." Early Hawaiians carefully crafted large koa into war canoe (wa‘a). Koa wood was also used in home construction and to make spears, paddles, kahili handles, and calabashes (‘umeke lā‘au). The bark was used as dye to stain kapa a red color. Medicinally, young koa leaves were used to ease cramps or fevers. Koa is drought and wind tolerant, but does not tolerate salt, over-watering, or shade.
