Yes, the banana fruit is a berry. Berries are identified as being many seeded with a fleshy inner layer. So, technically a banana is a berry. And, believe it or not, bananas don't grow on trees! Originally from Asia, the "banana tree" is really not a tree in the true sense. In fact, banana plants have no wood fiber. The banana plant is the world's largest herb and a member of the lily family. Bananas grow in tropical areas all around the world where the weather is sunny and hot, and there's plenty of rain.
