Rex Begonia

Rex Begonia is a rhizomatous begonia grown almost entirely for its extraordinary leaves rather than its flowers. The large, asymmetrical leaves come in dazzling combinations of silver, purple, burgundy, pink, and green, often with metallic sheens and spiraled bases.

A huge range of named hybrids exists, all derived from Begonia rex and related species. The plants are compact and clump-forming but appreciate the warmth and humidity of their tropical origins, which makes them a bit more demanding than typical houseplants.

Recognize it by:

• Leaves: large, asymmetrical, often with a spiraled or 'snail-shell' base; brilliantly patterned in silver, purple, pink, green, and burgundy
• Texture: somewhat puckered or quilted, sometimes with a metallic shimmer; undersides often reddish and hairy
• Habit: low, clumping, spreading from a surface rhizome
• Stems: short; growth arises from a creeping rhizome rather than tall stems
• Flowers: small pink or white blooms, secondary to the foliage and often removed

Light: Bright indirect light brings out the best leaf color; avoid direct sun, which scorches the foliage.

Water: Keep lightly moist, letting the top of the soil dry slightly. Water at the base to keep foliage dry, as wet leaves invite mildew.

Soil: Light, airy, well-draining mix; the shallow rhizome prefers a wide, shallow pot.

Temperature: 65-80F (18-27C); dislikes cold.

Humidity: High humidity is ideal, but ensure good airflow to prevent powdery mildew.

Feeding: Diluted balanced fertilizer during the growing season.

Propagation: Easy from leaf cuttings (leaf or leaf-vein cuttings) and rhizome division.

Begonia rex is native to eastern Asia, particularly the forests of northeastern India and surrounding regions, where it grows on the humid, shaded forest floor and among rocks.

The countless hybrids are grown worldwide as indoor foliage plants, in terrariums, and as shade plants in containers in mild climates.

Grown purely as an ornamental foliage plant, prized among the most striking of all houseplants for its kaleidoscopic leaves used in terrariums, shaded containers, and collections.

It has no significant culinary or medicinal use and is valued solely for its decorative impact.
