Calabash tree is a plant with a broad global footprint. Native to the major regions of Central America and the northern parts of South America, calabash tree has been cultivated in various other tropical regions. In the native range, calabash tree's cultivation has meshed well with local ecosystems, but as it is introduced to other continents such as Africa, Asia, and Oceania, the plant's impact is delicately managed to avoid ecosystem disruption. Notably, in areas like the Pacific islands, calabash tree may have an impact on local ecosystems, highlighting the delicate balance required when it transcends its native confines.
