Philodendron longilaminatum (Big)

A distinctive climbing Philodendron from South American rainforests, producing exceptionally long, narrow, lance-shaped leaves in deep glossy green with a slightly undulate margin and a graceful, arching posture — an elegant and uncommon species prized for its refined, elongated leaf form.

• Light: Bright indirect light; tolerates moderate light but produces its longest, most impressive leaves with better brightness. Avoid direct sun.
• Temperature: Warm-growing; thrives between 65–85°F (18–29°C). Protect from temperatures below 60°F (15°C) and cold drafts.
• Humidity: High humidity preferred, ideally 60–80%. Higher humidity encourages more vigorous growth and larger leaf development.
• Watering: Allow the top inch of soil to dry between waterings. Avoid waterlogging — ensure excellent drainage to prevent root rot.
• Growth Habit: Vigorous climber that develops increasingly long leaves as it ascends. A moss pole or totem is recommended — keeping it moist encourages aerial root attachment and maximizes the plant's characteristic elongated leaf form.

Additional Notes:

Best grown in a chunky, well-draining mix of orchid bark, perlite, and potting soil. The narrow, elongated leaf shape becomes more pronounced as the plant matures and climbs — install a moss pole early for best results. Repot every 1–2 years in spring when roots become crowded.
