Physalis alkekengi (bladder cherry, Chinese lantern, Japanese-lantern, strawberry groundcherry, or winter cherry; Japanese: hōzuki，中文：酸浆，姑娘，菇茑，姑鸟儿) is a relative of P. peruviana (Cape gooseberry), easily identifiable by the larger, bright orange to red papery covering over its fruit, which resemble paper lanterns. It is native from southern Europe east across southern Asia to Japan. It is an herbaceous perennial plant growing to 40–60 cm tall, with spirally arranged leaves 6–12 cm long and 4–9 cm broad. The flowers are white, with a five-lobed corolla 10–15 mm across, with an inflated basal calyx which matures into the papery orange fruit covering, 4–5 cm long and broad.
