About Rex begonia
Rex Begonias are a group of hybrids within the Begonia genus, prized for their spectacular and colorful foliage, often displaying intricate patterns, varied textures, and vibrant shades of green, red, silver, and purple. They are ideal houseplants for adding a touch of drama and color to any space, especially on shelves or tables where their leaves can be admired up close. Their beauty lies almost exclusively in their leaves, as their flowers are usually small and inconspicuous.

Care tips
They require bright, indirect light; direct sunlight can scorch their delicate leaves. Keep the potting mix consistently moist but avoid waterlogging, as they are very susceptible to root rot; allow the top layer of soil to dry out between waterings. They prefer a well-draining, organic-rich potting mix. A common mistake is insufficient humidity, which can lead to dry, crispy leaf tips, so they benefit from humid environments.
