* The calabash (not to be confused with the calabasa) 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.
