Physalis is a genus of flowering plants in the nightshade family, known for their distinctive lantern-like husks. These husks encase small, round fruits that can be edible or toxic, depending on the species. Common edible varieties include cape gooseberry and ground cherry, which are enjoyed for their sweet and tangy flavors. The plants typically grow as annuals or perennials and thrive in warm climates. They are often found in gardens and can be recognized by their bright yellow or orange fruits, which are surrounded by a papery shell. Physalis is also valued for its nutritional benefits, including vitamins and antioxidants.
