Bright filtered light (behind a sheer curtain, or set back 2-3 feet from a sunny window. A grow light 8-10 inches away works well) with protection from hot direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute). Place within 3 feet of a window; east or west-facing windows tend to work well.Light

Water moderately during active growth; allow soil to become fairly dry between waterings -- more drought tolerant (can go 2-3 weeks without water once established. When in doubt, wait another few days) than many begonias. Sudden temperature changes combined with inconsistent watering cause leaf drop.Water

Prefers 50-70% humidity; does not do well in dry air. Avoid direct misting (note: misting does not actually raise humidity meaningfully. A pebble tray or humidifier is more effective). Use a humidifier or pebble tray.Humidity

Metallic Leaf Begonia

Begonia metallica

Moderate

Begonia metallica is a shrub-like species from Bahia, Brazil, with leaves that genuinely look like polished metal -- they shimmer with an iridescent sheen that shifts between deep purple and olive-green depending on the angle of the light. New growth comes in bright red on both sides, maturing to dark green with red veins on the underside, and in summer and fall the plant produces clusters of pink flowers with darker, almost-red hairs. It is an upright grower that rewards a well-lit spot with dramatic color and a generous flowering season.

Fun Facts

Begonia metallica was first described in London's Floral Magazine in 1876 and quickly became a parent plant for breeders -- the earliest recorded hybrid, B. 'Margaritae,' was created in France before 1882 by crossing it with B. echinosepala.

Pet Safety

Toxic to pets

Toxic to dogs, cats, and horses per ASPCA. Toxic principles are soluble calcium oxalates; can cause vomiting and salivation in dogs and cats and kidney failure in grazing animals. The roots are the most toxic part.
