Solanum agrimoniifolium (agrimoniifolium meaning that the leaves are similar to those of the genus agrimonia) is native primarily to Guatemala, also reaching into southern Mexico and Honduras, where it is primarily a cloud forest species. Plants ranging from 18 inches to 6 feet tall. Flowers blue to purple. Berries large and conical. Tubers small or sometimes entirely absent according to Correll (1962), who also notes that plants collected from Guatemala are larger and less pubescent. Tuber color ranges from white to purple.
The spelling of the specific epithet for this species varies, with both agrimoniifolium and agrimonifolium in common use, something to keep in mind when performing searches.
Plants are found at elevations of 6,200 to 11,200 feet (1900 to 3400 m) (Correll 1962).
Vega (1995) found that this species is less frost tolerant than domesticated potato.

I have found seeds of this species easy to germinate using the standard conditions for S. tuberosum.
Towill (1983) found that seeds of this species stored at 1 to 3 degrees C germinated at 100% after 15 years.
