Philodendron cf lupinum (Philodendron vanninii Croat ined.) – Rare Tropical Aroid with Dramatic Leaf Evolution
Velvety Foliage That Transforms Over Time
Philodendron cf lupinum, informally referenced as Philodendron vanninii Croat (ined.), is a rare hemiepiphytic climber prized for its striking leaf metamorphosis. Juvenile plants produce soft, velvety heart-shaped leaves with deep maroon undersides, while mature leaves evolve into obovate-hastate forms with glossy green tops and matte lower surfaces. Native to Amazonian rainforests, it thrives indoors with vertical support and consistent high humidity.

Etymology of Philodendron cf lupinum
Philodendron combines Greek "philo" (love) and "dendron" (tree), reflecting the species’ climbing habit. Lupinum means "wolf-like" in Latin, referring to the plant’s bold and wild visual impression. The "cf." prefix stands for "confer," meaning "compare to," indicating that the plant resembles Philodendron lupinum but may be a separate, yet-to-be-published species (Philodendron vanninii).
