Physalis alkekengi: Unveiling the Enigmatic Bladder Cherry

Physalis alkekengi, also known by various names such as Alkekengi officinarum, Physalis franchetii, Bladder Cherry, Chinese Lantern, Japanese Lantern, Strawberry Groundcherry, Winter Cherry, Bladder Herb, Devil’s Berry, Devil’s Bladder, Red Nightshade, Cape Gooseberry, Strawbery Tomato, or Strawberry-and-tomato, is a captivating herbaceous perennial plant belonging to the Solanaceae family. While most Physalis species are native to the Americas, Physalis alkekengi finds its roots in Asia, where it has a rich history and diverse uses.


Physalis alkekengi typically reaches a height of about 60cm or 2ft, showcasing its elegance in the garden. The plant bears delicate creamy-white flowers with a distinctive five-lobed corolla. However, the true allure of Physalis alkekengi lies in its unique fruit structure. As the flowers fade, the basal calyx undergoes a remarkable transformation, maturing into an enchanting orange papery covering that resembles a traditional Chinese lantern. These “lanterns” add a touch of whimsy and charm to the autumn landscape. The fruits develop in early autumn, and when fully ripe, they are edible. However, it is important to note that the calyx and other parts of the plant, including unripe fruits, contain toxic compounds and should not be consumed.
