Sweet potato – This is a popular plant cultivated in the tropical zone, and came to Europe thanks to Christopher Columbus. Has no spikes or produces poison. It would seem that is defenseless against herbivorous insects. However, these appearances. New research shows that after its leaf is bitten, the batata produces a chemical substance.
