Avocados Are Berries and Bananas Are Herbs

The classification of plants can often challenge our everyday assumptions about the foods we eat. For instance, the creamy avocado is botanically a single-seeded berry. This is because it develops from the single ovary of a flower and has a fleshy middle layer, known as the mesocarp, between the outer skin and the single seed. While its savory flavor often leads to its use in salads and other dishes as a vegetable, and even the USDA categorizes it as such for nutritional purposes, its botanical origins firmly place it in the fruit (Review) kingdom. This distinction highlights the difference between culinary and scientific classifications.

Similarly, the towering banana plant, which can reach heights of up to 15 meters, is not a tree. It is, in fact, the world's largest herbaceous plant. The reason for this classification lies in its stem. Instead of a woody trunk, the banana plant has a "pseudostem" which is made up of the tightly packed sheaths of its leaves. This structure means it is more closely related to plants like ginger and mint than to an oak or pine tree. The banana fruit itself also holds a botanical surprise; it is technically a berry because it is produced from a single ovary on the flower.
