Description
Solanum flahaultii is a Colombian species, possibly reaching slightly into Venezuela. Plants reach about 18 inches tall. Flowers purple or violet. Conical berries. Tubers small and whitish. Found in rich soils at elevations of 8,850 to 12,000 feet (2700 to 3650 m).
The specific epithet, flahaultii, honors French botanist Charles Flahault. While there is no completely standardized pronunciation for scientific names, the most common way to pronounce this species is probably so-LAY-num fla-HOLE-ee-eye.
S. colombianum and S. flahaultii are closely related and may either be part of the same species or may interbreed where their ranges overlap.

Cultivation
I have found seeds of this species slow and difficult to germinate using the standard conditions for S. tuberosum.
Breeding
EBN has not been established for this species, but it will almost certainly be either 2EBN or 4EBN. There are AP polyploids with both EBN levels.
