Philodendron eximium
E Brazil
Philodendron eximium is a tropical South American aroid first described in the 19th century. It is native to the wet forests of Colombia and Ecuador, where it grows as an epiphytic climber in the canopy. The species exemplifies the genus's tendency to undergo dramatic leaf shape change (heterophylly) as plants mature from juvenile to adult form.
Prefers bright indirect light and consistently moist (not waterlogged) soil with excellent drainage. Loves humidity and appreciates moss pole or trellis support as it is a natural climber. Feed monthly during spring and summer, and reduce watering in winter.
Aroid mix: 50% orchid bark, 35% coco coir, 15% perlite. Prefers a slightly snug pot but repot every 1–2 years in spring when roots begin to circle. Provide a moss pole or trellis for optimal growth; climbing support encourages larger leaf production.
Monthly during growing season (spring–summer)
- Root rot from overwatering; spider mites in low humidity; yellowing lower leaves if light is insufficient; brown leaf tips from low humidity or mineral buildup in water
- Philodendron eximium produces distinctly lobed or deeply pinnatifid leaves as it matures, a characteristic that develops more dramatically with age and proper support.
- The name 'eximium' is Latin for 'exceptional' or 'distinguished,' reflecting its striking foliage.
- This species is an excellent candidate for moss pole cultivation, rewarding climbers with larger, more architecturally interesting leaves.
