Physalis

A member of the nightshade family of plants, physalis resembles a tomato in many ways: size, structure, shape. The strange differentiating factor is that physalis is found inside papery husks that look like tissue paper or dried leaves. As for taste, physalis fruit are generally mild with summery acidity, not unlike a strawberry or a cross between a tomato and a pineapple. Physalis is easy to grow thriving even in poor soil or a pot and a commercially cultivated version is the tomatillo, generally small, green, and encased by a thin papery husk.
