Solanum ×blanco-galdosii is only known from northern Peru (Depts. Ancash, Cajamarca and La Libertad), on eroded slopes, near field crops in dry soils, 2700-3260 m in elevation.
Solanum ×blanco-galdosii is a member of Solanum sect. Petota Dumort., the tuber-bearing cultivated and wild potatoes. Within sect. Petota, Solanum ×blanco-galdosii is a member of a distinctive clade of southern Ecuadorian and Peruvian species formerly classified in series Piurana and some other series that frequently possess moniliform tubers and shiny coriaceous leaves. On a higher taxonomic level, it is a member of the informally-named Potato Clade, a group of perhaps 200-300 species that also includes the tomato and its wild relatives (Bohs, 2005).

Solanum ×blanco-galdosii is morphologically similar to S. anamatophilum. Both species possess narrow lanceolate leaflets and lilac to blue corollas. They differ because S. ×blanco-galdosii has interjected leaflets and S. anamatophilum does not. According to Ochoa (1999) S. ×blanco-galdosii is a hybrid species originating from the cross between S. peloquinianum (now S. anamatophilum) and S. chomatophilum.
