A lantern fruit primarily refers to the distinctive fruit of the Chinese lantern plant, botanically known as Physalis alkekengi. It is renowned for its unique, lantern-like appearance, which makes it a popular ornamental plant.
Understanding the Lantern Fruit
The most striking feature of a lantern fruit is not the berry itself, but the large, papery husk that encases it. This husk, botanically a persistent calyx, develops into a vibrant, inflated covering that is typically bright orange to red. Its delicate, papery texture and lantern-like shape give the plant its memorable name.
