'Jack's Giant' is native to East Asia and India, and certainly lends a big splash of tropical flair to any garden setting. Reaching at least 7 feet tall and 5 to 8 feet wide, it thrives in moist to boggy or even wet soils, prefering those that are well enriched with organic matter. In wintertime, however, it needs much drier conditions to keep from rotting. Good drainage and consistent moisture is the solution, with a siting in sun to light shade.
