Physalis peruviana, a plant species of the genus Physalis in the nightshade family Solanaceae, has its origin in Peru. The plant and its fruit are commonly called Cape gooseberry, goldenberry, and physalis, among numerous regional names.
Physalis is a genus of flowering plants in the nightshade family (Solanaceae), which grow in warm temperate and subtropical regions of the world. Most of the species, of which 75–90 may exist, are indigenous to the Americas. The history of Physalis cultivation in South America can be traced to the Inca. Cultivated species and weedy annuals have been introduced worldwide. P. peruviana is closely related to the tomatillo and the Chinese lantern, also members of the genus Physalis. As a member of the plant family Solanaceae, it is more distantly related to a large number of edible plants, including tomato, eggplant, potato, and other members of the nightshades. Despite its name, it is not botanically related to other gooseberries. P. peruviana is an economically useful crop as an exotic exported fruit and favored in breeding and cultivation programs in many countries.
