Solanum crispum is a species of flowering plant in the family Solanaceae. It is native to Chile and Peru. Common names include Chilean potato vine, Chilean nightshade, Chilean potato tree and potato vine. Growing to 6 m (20 ft) tall, it is a semi-evergreen, woody-stemmed climbing plant. The small blue fragrant flowers, 2.5 cm in diameter, with prominent yellow ovaries, appear in clusters in summer. They resemble those of the closely related potato. Very small poisonous berries are produced in autumn. The berries start out green, then yellow-orange, and finally purple. The leaves are oval.
