Ficus triangularis, sold as Triangle Ficus, is a member of *Ficus*, a tropical and subtropical genus of about 850 species in Moraceae. A West African Ficus with distinctive triangular dark-green leaves on slender branching stems. The 'Variegata' cultivar with cream-edged triangular leaves is the most-traded form. Most cultivated Ficus tolerate bright filtered light and even moisture, and respond to sudden changes in light or watering with sometimes-dramatic leaf drop — settle the plant in one stable spot for best results.

Overview
Ficus triangularis sits in Ficus, one of the largest plant genera and the source of fig fruits, banyan-style stranglers, and most popular indoor trees. A West African Ficus with distinctive triangular dark-green leaves on slender branching stems. The 'Variegata' cultivar with cream-edged triangular leaves is the most-traded form. All Ficus produce a milky white latex when stems or leaves are cut — the latex is genus-typical and stains both clothing and skin if rubbed in.
Care Priorities
- Bright filtered light keeps growth vigorous.
- Even moisture; let the top 3 cm dry between waterings.
- Avoid sudden moves or temperature swings — Ficus drops leaves dramatically after stress.
- Wipe leaves monthly to keep stomata clear and check for spider mites.
Common Problems
Sudden leaf drop after a move or temperature change is the species' classic stress response — new leaves emerge once conditions stabilise. Brown leaf edges signal dry air. Sticky residue on lower leaves indicates scale or mealybug infestation on the stems above.

Frequently asked questions
Why are the leaves triangular?
F. triangularis leaves are genuinely triangular with a flat apex and tapered base, giving the species its name. The shape is genetic and species-typical, distinguishing F. triangularis from rounder-leaved relatives like F. benjamina or F. microcarpa.
Why does my Ficus drop leaves after I move it?
Ficus is famously sensitive to changes in light, watering, or temperature, and drops a flush of leaves as a stress response. Settle the plant in one bright stable spot, water consistently, and new leaves typically emerge within a month. Resist the urge to move the plant again during recovery.
How do I propagate a Ficus?
Ficus root readily from stem cuttings or by air-layering. Take a cutting with at least three nodes, dip the cut end in rooting hormone, and pot in moist propagation mix. Air-layering produces larger rooted specimens but takes longer (2 to 3 months) before the new root system is ready to sever from the parent.
