Malus
Apple trees are small, usually 4–12 m tall when full grown. The leaves are 3–10 cm long, positioned opposite from each other. They have a simple shape with a saw-tooth edge. The flowers come from corymbs, and have five petals, which may be white, pink or red, with usually red stamens that produce lots of pollen, and an ovary which is below them. Flowering takes place in the spring and pollination is by insects (typically bees, which freely visit the flowers for both nectar and pollen).
