Description

Native to the states of Michoacan and Jalisco in Mexico, where it is primarily found in pine and oak forests and as a weed of cultivated fields.  Plants range from just a few inches to about three feet tall.  White flowers.  Berries are unusual, very long and tapering.

This species can survive frosts down to 26 degrees F (-3.5 C) (Li 1977).  Vega (1995) found that this species is about as frost tolerant as domesticated potato.
