Rex begonias are prized for their bright and colourful foliage patterns more than their flowers.
Lighting: Grow Rex begonia in a medium to bright spot as a houseplant.
Watering: Water Rex begonias when the potting mix just dries. It's better to keep them a little too dry than too wet; they can rot if the soil doesn't dry out well enough.
Humidity: Rex begonias don't require quite as much humidity as many other exotic houseplants, but if your home has dry air, boost humidity in the winter months to keep the leaf tips from turning brown and dry.
Fertilization: Fertilize them as little as once or twice a year with a general purpose fertilizer.
