Description

Solanum cajamarquense distribution Map note

Solanum cajamarquense (cajamarquense indicating that it comes from the region of Cajamarca, Peru) is an unusual speces, native to mid-elevations of the Andes from about 6500 to 8500 feet.  Plants roughly 16 to 20 inches tall.  Stolons long, exceeding two feet.  Tubers small and moniliform, like beads on a string.  Berries small, less than 1/2 inch, round, striped.

S. cajamarquense appears to have unique late blight resistance genes (Lindqvist-Kreuze 2010).  Vega (1995) found that this species is about as frost tolerant as domesticated potato.

Li (2018) placed this species in Clade 3, a group of Andean diploids, but closely neighboring Clade 1+2, North American 1EBN diploid species.

Cultivation

I have found germination of this species to be very slow, taking between one and three months.

The pesticide carbofuran has been observed to reduce flowering in this species (Centeno-diaz 2007).
