The Koa tree (Acacia koa) is a native tree species found primarily in the Hawaiian Islands. It is known for its tall stature, reaching heights of up to 100 feet, and its distinctive, curved trunk. The tree has dark green, feathery leaves and produces yellow flowers that attract various pollinators. Koa wood is highly valued for its strength and beautiful grain, making it popular for furniture and musical instruments, such as ukuleles. The Koa tree plays a crucial role in the Hawaiian ecosystem, providing habitat and food for native wildlife, including birds and insects.
