Philodendron atabapoense was something of a source of confusion a few years back. Being called everything from “santa leopoldina II” to superbum. The leaves are extremely variable having bright red backs when juvenile and fading to green as it climbs.
Formally described in 1975, Philodendron atabapoense is found primarily in the Amazonia region of Brazil and the southern portion of Venezuela. Typically, the species is found at an elevation of approximately 100 meters above sea level, this makes for a warm growing plant that is easy to grow. 4″ pots, leaves on the plants we have available are about 8-10″ long
