A Trending Variegated Fig

Variegated Ficus triangularis is a distinctive, relatively uncommon member of the ficus tribe, closely related to the fiddle-leaf fig. It carries thick, waxy, triangular leaves edged in creamy white, with each leaf marked a little differently from the next.

Light, Water, and Feeding Rhythm

This plant wants as much bright, indirect light as you can give it, though it will tolerate medium light and even grows under fluorescent or LED bulbs; direct sun, especially in southerly regions, can scorch the pale variegated edges. Let the top several inches of potting mix dry before watering again, and avoid overwatering. Average to above-average humidity suits it best, so a pebble tray, nearby humidifier, or grouping with other plants helps when indoor air runs dry. Feed in spring and summer with a houseplant fertilizer, following label rates, since excess can injure the roots.

Triangular, Two-Toned Foliage

The defining trait here is the leaf shape itself, a triangle rather than the oval or lobed forms typical of other ficus. Foliage comes in quantity, green shot through with cream, and is held up on stiff, compact stems. Grown indoors it starts as a compact tabletop plant but, with time, matures into a proper small tree.

Pruning for Fullness

Pruning isn't strictly necessary for this ficus, but pinching or trimming can help shape it. If light is a bit low and stems stretch out long and lanky, periodic pinching back encourages a fuller, bushier habit instead.
