Rex begonias are grown for leaves, not flowers: swirls of silver, pink, purple, red, and green in patterns that look hand-painted. Each plant reads like a small piece of artwork on a windowsill or desk.

Give it bright, indirect light indoors; direct sun scorches the foliage. Let the top inch of soil dry between waterings, and keep it in a well-draining mix away from cold drafts. It appreciates humidity, so a kitchen or bath window suits it well.
