What is Polka Dot Begonia?

Polka Dot Begonia is native to South America and is a member of the begonia family. It is a popular houseplant famous for its low maintenance and ease of care. The plant can grow up to 18 inches tall and wide, making it ideal for a windowsill, tabletop, or hanging plant.

Begonia Maculata Varieties

There are several varieties of Maculata Begonia, each with its unique characteristics. Some of the popular types include:

Pink Polka Dot Begonia

This variety has green leaves with pink dots and produces pink or white flowers.

Scarlet Polka Dot Begonia

This variety has green leaves with red dots and produces red or pink flowers.

Wightii Polka Dot Begonia

This variety has dark green leaves with silver dots and produces white flowers.

Polka Dot Care

Caring for the Polka Dot is simple and straightforward. Here are some of the key factors to keep in mind:


The Begonia thrives in bright, indirect light. It is best to place it near a window that gets bright light but is protected from direct sun exposure. If the plant isn’t getting enough light, the leaves may become thin and leggy and may stop the polka dot begonia flowering process.


Keep the Polka Dot consistently moist but not waterlogged. It’s best to check the soil regularly and water the plant when the top inch of the soil is dry. Make sure to use a well-draining soil mixture, and avoid letting the plant sit in standing water, which can lead to root rot.


The Begonia prefers high humidity, so it’s a good idea to place a humidifier near the plant or set the pot on a tray filled with water and pebbles. Alternatively, you can mist the plant regularly.


Begonia Maculata, also known as Polka Dot Begonia, is a tender perennial native to subtropical regions of South America. While it can tolerate some degree of temperature fluctuation, it is best to keep it in a warm and consistent environment with temperatures between 60°F and 80°F. 

However, it is more tolerant of cool temperatures than extreme heat. Avoid exposing it to temperatures below 50°F, as this can cause damage to the plant, and sudden temperature drops can cause the leaves to turn yellow and fall.


A well-draining soil mixture is crucial for the health of your Polka Dot Begonia. A good blend would be two parts of peat moss or coir, one part perlite or sand, and one part compost or well-rotted manure.


Avoid overfertilizing, which can lead to stunted growth and yellowing leaves.-Polka Dot Begonias benefits from regular fertilizing during the growing season. You can use a balanced, water-soluble fertilizer every 2-4 weeks, following the instructions on the package.


Repot Begonia Polka Dot every 2-3 years to ensure it has room to grow and to freshen up the soil. When repotting, choose a pot that’s 1-2 inches larger than the previous pot, and use a well-draining soil mixture. Water the plant thoroughly after repotting it and place it in a bright, indirect light.

Polka Dot Propagation

The Polka Dot is a relatively easy plant to propagate, making it an excellent choice for gardeners who want to expand their collection or share it with friends and family. The easiest way to propagate Polka Dot Begonia is through stem cuttings. Here’s a step-by-step guide on how to propagate Polka Dot Begonia:


  • Sharp scissors or pruning shears
  • 4-6 inch stem cuttings from a healthy Polka Dot Begonia plant
  • Well-draining soil mixture
  • Pot with drainage holes
  • Humidity dome or plastic bag (optional)


  1. Select a healthy stem cutting from your Polka Dot Begonia plant, cutting 4-6 inches long, just below a node (the point where a leaf attaches to the stem).
  2. Remove the lower leaves, leaving just a few leaves on the top of the stem.
  3. Dip the cut end of the stem into the rooting hormone, if desired, to promote faster root growth.
  4. Fill a pot with a well-draining soil mixture, making a hole in the center.
  5. Insert the cut end of the stem into the soil, gently firming the soil around it.
  6. Water the cutting thoroughly and place it in bright, indirect light. If desired, you can cover the pot with a humidity dome or plastic bag to help retain moisture and increase humidity.
  7. Check the soil regularly and keep it moist but not waterlogged.
  8. In a few weeks, roots will start to form, and the new plant will be ready to transfer to its permanent pot.
