The genus Physalis consists of some 80 annuals and perennials, characterised by their very distinctive papery sacs (lanterns or calyces) which completely surround the fruits. Originating from North and South America, Asia and Europe, several species have edible fruit, a few well known such as the cape gooseberry and tomatillo. Some of the perennial types are considered weedy in some climates. This article considers the edible species and other species of use.
