Solanum limbaniense (limbaniense for the Limbani region of the Sandia province of Peru) is a species with a small distribution in southern Peru, very near to the Bolivian border.  Plants typically about a foot tall.  Tubers small and whitish, reaching a little more than an inch in diameter.  Flowers light to dark purple.  Berries long and conical.

The specific epithet, limbaniense, refers to the Limbani region of the Sandia province of Peru.  While there is no completely standardized pronunciation for scientific names, the most common way to pronounce this species is probably so-LAY-num lim-bah-nee-EN-say.

This species grows up to very high elevations in the Puna, ranging from 9,500 to 12,300 feet (2900 to 3750 m) (Ochoa 2004).

Cultivation

I have found seeds of this species easy to germinate using the standard conditions for S. tuberosumBamberg (2018) found that alternating temperatures increased germination in this species.

Every flower on every plant formed a berry in 2018.  This species should probably be evaluated for self-compatibility.

Tubers have minimal dormancy, which led Ochoa (2004) to speculate that this species might have been involved in the evolution of S. phureja, but it doesn’t appear that subsequent genetic studies have borne that out.
