In New Zealand, I. globosa is common in the upper North Island, but becomes uncommon in south of Manawatu River. In the South Island, it is only found on the West Coast at Mahers Swamp. [2]

I. globosa is strictly a wetland plant, existing on the edges of swamps and lake margins, or in deep gullies. [5] Throughout much of Asia, I. globosa is a weed of rice paddies, often impacting rice yield. [6]
