Understanding Rex Begonias

Rex Begonias are a popular houseplant known for their colorful and uniquely patterned leaves. They belong to the Begoniaceae family and are native to tropical regions. These plants are easy to care for and can bring a touch of beauty to any indoor space.

Characteristics of Rex Begonias

Rex Begonias are characterized by their large, asymmetrical leaves that come in a wide range of colors and patterns. The leaves can be smooth or textured, depending on the variety. These plants do not produce flowers but are prized for their foliage. Rex Begonias are typically compact and bushy, making them ideal for tabletop or hanging planters.

Popular Varieties of Rex Begonias

Some popular varieties of Rex Begonias include the Rex-cultorum hybrids, which are known for their vibrant colors and intricate patterns. The Escargot Begonia has spiral-shaped leaves, while the Iron Cross Begonia has distinctive silver markings. Other notable varieties include the Fireworks Begonia and the Tornado Begonia.

Growing Conditions for Rex Begonias

Rex Begonias thrive in bright, indirect light but can also tolerate lower light conditions. They prefer well-draining soil that is kept consistently moist but not waterlogged. These plants do well in humid environments, so misting the leaves occasionally can help to maintain the proper moisture levels. Rex Begonias also benefit from regular fertilization during the growing season to promote healthy growth.

Methods of Propagating Rex Begonias

Leaf Cuttings

One common method of propagating Rex Begonias is through leaf cuttings. To do this, simply take a healthy leaf from the plant and cut it into sections, making sure each section has a vein running through it. Plant the sections in a well-draining soil mix and keep them moist but not waterlogged. In a few weeks, roots should start to form, and you can then transplant the new plants into their own pots.

Stem Cuttings

Another way to propagate Rex Begonias is through stem cuttings. To do this, cut a healthy stem from the plant and remove any leaves from the bottom few inches. Place the stem in a container of water or directly into a well-draining soil mix. Keep the soil moist and in a few weeks, roots should start to form. Once the roots are established, you can transplant the new plants into their own pots.


Dividing Rex Begonias is another method of propagation that can be done when repotting the plant. Simply remove the plant from its pot and gently separate the root ball into smaller sections, making sure each section has some roots attached. Plant the sections in their own pots with fresh soil and water thoroughly. With proper care, the divided sections should grow into healthy new plants.

Caring for Newly Propagated Rex Begonias

When propagating Rex Begonias, it is important to provide the right care to ensure their successful growth. Here are some tips on caring for newly propagated Rex Begonias:

Potting Mix and Containers

Choose a well-draining potting mix that is rich in organic matter for your newly propagated Rex Begonias. A mix of peat moss, perlite, and vermiculite works well for these plants. Make sure the containers have drainage holes to prevent waterlogging, which can lead to root rot.

Light and Temperature Requirements

Rex Begonias thrive in bright, indirect light. Avoid exposing them to direct sunlight, as this can scorch their delicate leaves. Maintain a temperature of around 65-75°F (18-24°C) for optimal growth. Keep them away from drafts or sudden temperature fluctuations, as these can stress the plants.

Watering and Feeding

Water newly propagated Rex Begonias when the top inch of the soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. Fertilize the plants with a balanced liquid fertilizer diluted to half strength every 4-6 weeks during the growing season. Reduce feeding during the winter months when the plants are dormant.

By following these care tips, you can help your newly propagated Rex Begonias thrive and flourish in their new environment.


In conclusion, propagating Rex Begonias can be a rewarding and enjoyable process for plant enthusiasts. By following the proper techniques and providing the right conditions, you can successfully grow new plants from cuttings or divisions. Remember to be patient and attentive to the needs of your Begonias, and soon you will have a beautiful collection of these unique and stunning plants. Whether you are a seasoned gardener or a beginner, propagating Rex Begonias is a fun and fulfilling way to expand your garden and share the beauty of these plants with others.
