Solanum lignicaule distribution Map note

Solanum lignicaule (lignicaule meaning “woody stem”) is a species with a small distribution in southern Peru.

This species can survive frosts down to 27 degrees F (-3 C) (Li 1977).  Vega (1995) found that this species is less frost tolerant than domesticated potato.
