Bottle Gourd
    The calabash is a vine grown for its fruit, which can either be harvested young and used as a vegetable or harvested mature, dried, and used as a bottle, utensil, or pipe. For this reason, one of the calabash subspecies is known as the bottle gourd. The fresh fruit has a light green smooth skin and a white flesh.

The calabash was one of the first cultivated plants in the world, grown not for food but as a container. It was named for the calabash tree (Crescentia cujete), a different type of plant.
