JACKFRUIT TREE Organic Grown. I have 8 ~12" seedlings. These tropical beauties make great Indoor/Patio plants, and, may bloom in another 6 years. Fruit production is more likely if planted outside. They can exceed 100' in height, if left to their own devices, but, can be trimmed to a tall hedge for easier fruit harvest. Although, that wouls severely impact the quantity of fruit.
