philodendron Barrosoanum

Juvenile Form: Young plants begin with simple, elongated, lance-shaped, or arrow-shaped green leaves.
Mature Form: As the plant climbs, it undergoes dramatic morphogenesis. Mature leaf blades become distinctly tri-lobed (three-lobed), featuring a long, prominent central lobe and two backward-pointing side ears (hastate shape).
Texture & Size: The semi-glossy, dark green leaves are sub-coriaceous (slightly less than leathery) and can grow up to half a meter long on a well-supported plant.
Light: Prefers medium to bright indirect sunlight. Avoid harsh, direct sun to prevent leaf scorching.
Watering: Allow the soil to dry out almost completely between waterings. It is an easy-going, drought-tolerant species that is highly susceptible to root rot if left in waterlogged soil.
Soil: Use a chunky, highly aerated aroid mix containing standard potting soil mixed with orchid bark, perlite, and charcoal.
Climate: Thrives in standard household temperatures between 18°C and 26°C. While it enjoys moderate to high humidity (50–70%), it adapts remarkably well to average living room conditions.
Toxicity: Toxic to pets and humans. The plant contains calcium oxalate crystals which cause severe mouth swelling and digestive discomfort if chewed.
