Habitat Notes Taro was probably first native to the lowland wetlands of Malaysia (taloes). Estimates are that taro was in cultivation in wet tropical India before 5000 B.C., presumably coming from Malaysia, and from India further transported westward to ancient Egypt, where it was described by Greek and Roman historians as an important crop. An Australia, Colocasia esculenta var. aquatilis is native to the Kimberley region of Western Australia; variety esculenta is naturalised in Western Australia, the Northern Territory, Queensland and New South Wales. Cultivated on Rapa Nui (Easter Island)
