|cape gooseberry (Physalis peruviana) leaves and fruit|

Physalis (//, sometimes //) is a genus of plants in the nightshade family (Solanaceae), native to warm temperate and subtropical regions of the world. All but one species are native to the New World, and most species occur in Mexico in particular. At least 46 species are endemic to the country. The genus is characterised by the small orange fruit similar in size, shape and structure to a small tomato, but partly or fully enclosed in a large papery husk derived from the calyx. Many Physalis species are called groundcherries. One name for Physalis peruviana is cape gooseberry, not to be confused with the true gooseberries, which are of the genus Ribes in the family Grossulariaceae.
They are herbaceous plants growing to 0.4 to 3 meters tall, similar to the common tomato, a plant of the same family, but usually with a stiffer, more upright stem. They can be either annual or perennial. Most require full sun and fairly warm to hot temperatures. Some species are sensitive to frost, but others, such as the Chinese lantern, P. alkekengi, tolerate severe cold when dormant in winter.
Cultivation and uses
These plants grow in most soil types and do very well in poor soils and in pots. They require moisture until fruiting. Plants are susceptible to many of the common tomato diseases and pests, and other pests such as aphids, whiteflies, spider mites, and the false potato beetle (Leptinotarsa juncta) also attack them. Propagation is by seed. Some species are self-incompatible and require pollen from other plants to bear fruit.
Not all Physalis bear edible fruit. Select species are cultivated for their edible fruit, however; the typical Physalis fruit is similar to a firm tomato in texture, and like strawberries or pineapple in flavor, with a mild acidity. Some species, such as the cape gooseberry and tomatillo have been bred into many cultivars with varying flavors, from tart to sweet to savory. Physalis fruit are rich in cryptoxanthin.
The fruit can be used like the tomato. Once extracted from its husk, it can be eaten raw and used in salads. Some varieties are added to desserts, used as flavoring, made into fruit preserves, or dried and used like raisins. They contain pectin and can be used in pie filling.
The cape gooseberry is native to the Americas, but is commonly in many subtropical areas. Its use in South Africa near the Cape of Good Hope inspired its common name. Other species of commercial importance include the tomatillo (P. philadelphica). Some nations, such as Colombia, have a significant economic trade in Physalis fruit.
In Chinese medicine, Physalis species are used as remedies for such conditions as abscesses, coughs, fevers, and sore throat. Smooth groundcherry (P. subglabrata) is classified as a hallucinogenic plant, and its cultivation for other than ornamental purposes is outlawed in the US state of Louisiana under State Act 159.
The extinct Dacian language has left few traces, but in De Materia Medica by Pedanius Dioscorides, a plant called Strychnos alikakabos (Στρύχνος άλικακάβος) is discussed, which was called kykolis (or cycolis) by the Dacians. Some have considered this plant to be Physalis alkekengi, but the name more likely refers to ashwagandha (Withania somnifera).
