Physalis peruviana, commonly known as physalis, is indigenous to South America, but was cultivated in Mexico in the region of Puebla since 2006.

As a member of the plant family Solanaceae, it is related to a large number of edible plants, including tomato, eggplant and potato, and other members of the nightshades. It is closely related to the tomatillo but not to the cherry, Cape gooseberry, Indian gooseberry or Golden gooseberry, as its various names might suggest.

The fruit is a small round berry about the size of a marble with numerous small yellow seeds. It is bright yellow and sweet when ripe, making it ideal for snacks, pies or jams. It is popular in fruit salads, sometimes combined with avocado.

Its most notable feature is the single papery pod that covers each berry. Because of the fruit's decorative appearance, it is sometimes used in restaurants as an exotic garnish for desserts. If the fruit is left inside the husks, its shelf life at room temperature is over 30–45 days.
