Solanum laxum, commonly known as potato vine, potato climber or jasmine nightshade, is an evergreen vine in the family Solanaceae. It is native to South America and commonly grown as an ornamental garden plant. The ovate or ovate-lanceolate leaves are 30 to 50 mm long and 15 to 25 mm wide. The white or pale blue flowers appear in groups of around 20 in branched inflorescences, produced in profusion in the spring but also sporadically at other times of the year. These are followed by dark blue or black berries that are around 8 mm in diameter.
