Thaumatophyllum bipinnatifidum (formerly Philodendron bipinnatifidum), often called the Lacy Tree Philodendron, is a self-heading aroid native to subtropical South America. It forms a stout, trunk-like stem with age and produces impressive, deeply lobed, bipinnatifid leaves that can exceed 1 meter in length on mature specimens. Thick petioles and numerous aerial roots help anchor and support the plant as it becomes top-heavy. In habitat, it grows as a terrestrial plant in bright, dappled understory light and forest edges. Indoors, it is valued for its dramatic, architectural foliage and tolerance of typical household conditions. Given adequate space, warmth, and humidity, it can develop into a substantial specimen. The inflorescence consists of a spadix and spathe typical of Araceae, though flowering is uncommon indoors. While hardy in frost-free climates outdoors, it is generally kept as a container plant elsewhere. Handle with care: tissues contain calcium oxalate crystals that can irritate skin and mouth if chewed.

How to care for Lacy Tree Philodendron
Water
Water thoroughly, allowing excess to drain freely; never let the pot sit in a saucer of water. Let the top 2–5 cm (1–2 in) of the mix dry between waterings in warm seasons, slightly deeper in low light or cool rooms. In winter, reduce frequency but do not allow the root ball to desiccate. Use a porous, airy medium so roots remain oxygenated. If leaves droop and soil is dry, water; if they droop and soil is wet, wait and improve drainage.
Light
Provide bright, indirect light to dappled shade. A few hours of gentle morning sun are fine, but protect from harsh midday sun that can scorch lobes. In too little light, internodes stretch and new leaves emerge smaller; in excessive direct sun, leaves yellow and crisp at the edges. Indoors, place near an east-facing window or a bright north window; south/west exposures need sheer curtains. Under grow lights, target 8–12 hours/day at moderate intensity.
Nutrients
Feed during active growth (spring through early autumn) with a balanced, nitrogen-forward fertilizer at half strength every 2–4 weeks, or use a slow-release formulation per label rates. Aim for steady nutrition rather than heavy doses. Ensure micronutrients are present to prevent chlorosis; occasional magnesium and iron support can be helpful if leaves pale. Flush the potting mix with plain water every 6–8 weeks to prevent salt buildup. Withhold or greatly reduce feeding in winter when growth slows.
Temperature
Keep in warm conditions: 65–85°F (18–29°C) is ideal. Brief highs to the low 90s°F (32–34°C) are tolerated with adequate humidity and water. Avoid cold drafts and temperatures below 55°F (13°C); sustained chill can cause leaf damage and slowed growth. Outdoors in frost-free climates, provide shelter from cold winds. Indoors, avoid placement directly under AC vents or near heaters to prevent leaf edge browning from rapid temperature swings.
