Description

Solanum violaceimarmoratum (violaceimarmoratum meaning “purple mottled” and probably refers to the stems) is native to the eastern slopes of the Bolivian Andes, at elevations of roughly 6500 to 11200 feet.  An unusual species, thought not to be closely related to other wild potatoes.  Very tall plants, reaching nine feet in height.  Stolons three feet or more.  Tubers reaching two to three inches in length, more in cultivation.  Purple flowers.  Berries conical.

This species can survive frosts down to 27 degrees F (-3 C) (Li 1977), about the same as the domesticated potato.  Even though it grows at relatively high elevations, It has poor frost resistance compared to most wild potatoes, most likely because the eastern slopes of the Andes to which it is native are warmed by updrafts from the Amazon basin (Smillie 1983).

Cultivation

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

Breeding

Crosses with S. tuberosum

Watanabe (1991) found that 2.8% of varieties of this species produced 2n pollen, which would be effectively tetraploid and 4EBN.
