The coconut palm is a long-lived plant; it has a single trunk, 20-30 metre tall, its bark is smooth and gray, marked by ringed scars left by fallen leaf bases. The tree can live as long as 100 years producing an annual yield of 50 to 100 coconuts. Its flowers grow in clusters on a stem; a flowering structure known as an inflorescence. The female flowers are larger than the male flowers, and both are found on the same inflorescence.
