Have you ever wondered what a cashew tree or bush looks like? If you love snacking on this nut, then it is essential to know how and where it is grown. The cashew tree is native to Brazil, but now it is grown commercially in many parts of the world, including India, Vietnam, and Nigeria. It is a tropical evergreen tree that can grow up to 14 meters high, but is usually pruned to about eight meters for easier harvesting.
The leaves of a cashew tree are simple and leathery, with pointed tips. They are oblong or obovate in shape and about 4 to 22 centimeters long. The flowers are small and delicate, pale green or yellow, and grow on a panicle. The fruit is a green apple-like structure, which contains the cashew seed or nut. It takes about three months for the fruit to mature and turn yellow, eventually falling to the ground when ripe.
The cashew tree’s nuts are a familiar sight to people who enjoy their saltiness and nutty taste. The nut itself is kidney-shaped and attached to a curved stem called a cashew apple. These apples are not consumed as much as the nuts, but they are used in some countries to make a refreshing drink or wine. If you are lucky enough to see a cashew tree or bush in person, you may be surprised by their beautiful appearance and can’t help but admire their role in bringing such a delectable treat to tables around the world.
