Philodendron lupinum
Brazil (Acre)
Philodendron lupinum is a lesser-known aroid species native to Brazil. It was described and named by horticulturists working with tropical Araceae in the mid-20th century. The species remains rare in cultivation outside specialist collections, and its exact wild distribution is not well documented. It belongs to the larger Philodendron genus, which contains over 500 species.
Prefers bright, indirect light and consistently moist (not waterlogged) soil. Naturally a climber, so provide a moss pole or trellis for best growth and larger leaf development. Maintain humidity above 60% and avoid cold drafts below 18°C.
Aroid mix: 40% orchid bark, 40% coco coir, 20% perlite. Repot every 18–24 months in spring when roots circle the pot. Slightly snug is acceptable; prefers moisture-retentive but well-draining substrate.
Monthly during growing season (spring–summer)
- Root rot from overwatering or poor drainage; spider mites and mealybugs in low humidity; yellowing lower leaves from inconsistent watering or low light.
- Philodendron lupinum is a rare species with distinctive lobed leaves that develop more deeply when the plant climbs and matures.
- The species name 'lupinum' may derive from the Latin 'lupus' (wolf), though the exact etymology is unclear.
- Like many philodendrons, it produces larger, fenestrated leaves as it climbs higher on its support.
