Solanum laxissimum (laxissium meaning “loosest”) is a Peruvian species growing in eastern Andean forests.  Plants three to twelve feet tall and perhaps as much as 16 feet according to Correll (1962).  Tubers five to six inches long.  Flowers large and light to dark purple.  Berries conical, more than an inch long.  Forest edges at 6,900 to 10,200 feet (2100 to 3100 m) elevation.

Ochoa (2004) mentions that the berries are called shaullinco, but doesn’t discuss why they have a name.  If they are named, presumably they have some use.

Cultivation

I have found seeds of this species easy to germinate using the standard conditions for S. tuberosum.

Breeding

Jackson (1999) found 5% 2n pollen for varieties of this species.
