About Rex begonia

Its large, asymmetrical leaves display intricate patterns and a wide range of colors, including greens, reds, purples, and silvers, often with iridescent or velvety textures. It is ideal for indoor settings, adding an exotic and dramatic touch to any space, especially as a tabletop plant or on shelves where its foliage can be appreciated up close.

Care tips
It prefers bright, indirect light; direct sunlight can scorch its delicate leaves, while too little light will dull its colors. Keep the substrate consistently moist but not waterlogged, watering when the top layer feels dry to the touch, as it is prone to root rot. Use a well-draining, organic-rich potting mix; a common mistake is insufficient ambient humidity, so it benefits from a humid environment or a pebble tray with water nearby.
