Philodendron rubrijuvenile (aka Philodendron Choco Red) seedling

Surname: Philodendron rubrijuvenile
Synonyms: not known
etymology: rubrojuvenile = red in juvenile state
Reproduction: Division
Origin: Costa Rica, Panama, Colombia, Ecuador, Peru
Location: Usually hemiepiphytic, rarely terrestrial or epiphytic. Only reported from the Choco region of Colombia at altitudes of 500-1000 m.
Remarks: This species is one of many taxonomic problems in naming that have not yet been fully resolved. This species was discovered many years ago and offered by Ecuagenera as Philodendron verrucosum 'No.5.' due to its similarity to Philodendron verrucosum.
Due to its beautiful red coloring, it quickly became popular among collectors in the USA and was traded as Philodendron Choco Red based on its coloring and region of origin.
New investigations, which were only possible after prolonged cultivation of the plants and diagnosis of the flower structure, have led to Philodendron verrucosum 'No. 5' now being treated as a separate species, and it is currently described as Philodendron rubrijuvenilum (possibly also rubrojuvenilum) (as of June 2022).

The red coloring on the underside of the leaves is clearly visible in older plants when the plants are cultivated in brighter conditions. When cultivated in the shade, the underside of the leaves remains green - light green.
