Rex Begonia

Botanical Name: Begonia rex hybrids

A long-time favorite of house plant lovers, Rex Begonia is grown for its colorful, textured foliage. These fancy- leafed plants (such as the spiral-leaf, pictured here) produce dramatic, large leaves streaked, veined, or splashed in shades of silver, pink, purple, cream, green, or burgundy.

Tiny, insignificant flowers may grow on tall stems. Pinch them off as soon as you see them to keep the foliage looking its best.

This plant is rhizomatous, growing from a thick, fleshy rhizome that grows just below the surface of the soil. Repot when the rhizome outgrows the pot, using a shallow pot because of its shallow root system.

Rex begonia can be difficult to grow because of its need for high humidity.

These plants sometimes drop their leaves and become dormant in the winter. If this happens, cut off the withered leaves, stop watering, and enclose the plant in a plastic bag. Keep it at 60°F/16°C until new growth appears, in approximately 6-10 weeks. Then continue with normal care.

Origin: Asia and India

Height: Varies

Light: Bright light, but no direct sun which can scorch the leaves. Thrives under fluorescent light.

Water: Keep soil evenly moist at all times, but be careful not to overwater because the rhizomes are prone to rot in soggy soil. Avoid getting water on leaves because they may spot.

Humidity: High humidity. Increase humidity by standing pot on a tray of wet pebbles, or use a room humidifier. Do not mist because this can cause spots to form on leaves.

Temperature: Average room temperatures 65-75°F, 18-24°C

Soil: African violet potting mix works well.

Fertilizer: Feed every 2 weeks spring through fall with a balanced liquid fertilizer diluted by half.

Propagation: Leaf cuttings
