Rex Begonia

Posted on by

Rex Begonia, the “king” of begonias is also known as the “painted leaf” begonia for its beautiful variegated leaves that can grow up to six inches long and are available is shades of green, red, silver and purple.

This is a plant that you want for its leaves. Unlike flowering plants that may only bloom for a certain season, Rex Begonias provide year-round interest with their colorful foliage, making them a favorite among gardeners and plant enthusiasts. In fact, owners commonly pinch off the Rex Begonia’s not-that-impressive blooms so as to not distract from its dramatic foliage.

To encourage the most beautiful leaf color, you need to give your plant plenty of (indirect) light and pretty high humidity. Here are the basics to giving your Rex begonia the royal treatment it deserves.

Caring for Your Rex Begonia

  • Plant your Rex Begonia in light, fast draining soil.
  • Rex Begonias thrive with bright, indirect light year round. You don’t want to burn those gorgeous leaves, so no direct light. You also want to rotate the plant frequently to give it equal light on all sides.
  • This plant requires regular watering but be careful not to overwater. Let the soil surface become dry to the touch before watering. 
  • They also love humidity, but be careful if you decide to mist the leaves; if they stay wet, you might find yourself seeing powdery mildew. 
  • Rex Begonias like moderate temperatures in the 60-70 degree range.
