Physalis (weeds) L. - (ground-cherries)

This genus includes more than 100 species of herbs, many of them are common in tropical and subtropical parts of America. Some are cultivated like tomatillo (Physalis philadelphica or P. ixocarpa), but several species are regarded as agricultural or environmental weeds which spread and grow quickly. A number are also introduced outside their native range. For example Physalis angulata is introduced and alien in various regions, competes with native vegetation and affects field crops.

The plants usually grow up to a height of 20-50 cm and are characterised by the papery and balloon-like cover (lanterns) that surrounds the fruits. The flowers are bell-shaped, yellow with dark spots at the base of the petals.
