Philodendron planadense is known from the type locality near La Planada (hence the name P. planadense), Colombia (Narino), and also adjacent Ecuador (Carchi), at elevations of 1,750-2,265 m, in Premontane wet forest life zone. Apparently uncommon at La Planada, this species was collected in the regrowth forest along the trail above La Posada and in the swampy old pasture area south of the Sendero Natural, as well as in other sites not specifically described.
