An apple tree is generally a small tree. When untrimmed, it can reach 9 meters (30 feet) in height with a large crown diameter. Its bark is usually brown and scaly, and its simple, oval-shaped leaves have fine teeth along the edges. Apple flowers are showy, with five white petals often tinged with pink, and have numerous stamens. Bees and other insects pollinate the flowers; most varieties need cross-pollination for fertilization.
