Description

A widespread species in Mexico, where it is primarily a plant of woodlands and cloud forests. Plants about 6 to 18 inches tall. Blue flowers. Round berries.

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

S. verrucosum is suspected as the progenitor of all Mexican polyploid species, based upon the presence of a mitochondrial marker (Sanetomo 2013).
