A ripe fruit of bladder cherry
However, the unripe fruits can be toxic and therefore caution needs to be exercised while eating this fruit.
As the fruits are attractive, so bladder cherry is mostly grown for decorative purposes. But as the fruits are edible, so it is also cultivated for fruits.
The plants are raised from seed which is first sown in the nursery and then transplanted to field.
