Begonia Rex - Hybrids “Paint-Leaf Begonia”


Light: Keep begonias in the brightest indirect light available to you. Direct light can burn the leaves, not enough light increases the chance of rotting as well as fungal issues on the leaves.


Water: Water evenly once the top 50% of soil is completely dry, as they are sensitive to overwatering. Avoid getting water on the leaves. Shallow pots and pots with drainage are ideal to encourage plenty of aeration for the roots. During the winter, watering will be less frequent and a lower volume.


Environment: Begonias prefer around 50% humidity and temperatures of 60-70 degrees. Keep away from dry air, drafts, and cold windows. The most difficult part of a begonia is getting into a watering schedule, but once you find a rhythm, they are a spectacular indoor and outdoor plant in the warmest months! If outdoors, keep near shade. Indoors, avoid cool temperatures and try to avoid any drafts or fluctuations of environmental factors.


Toxicity: Reported to be Mildly toxic if ingested 


Of Note:

  • Rex Begonias account for hundreds of hybrids, and their forms are too numerous to count. The resulting plants are often known by multiple names from grower to grower.
  • Some fall dormant in autumn and will show decreased growth.
While the foliage is the main attractor, they also have delicate, beautiful flowers. These can be removed to encourage further foliage growth.
*When planting in a pot without a drainage hole, avoid over watering by estimating 25% of the container’s overall volume, with appropriate drainage materials incorporated when planting.
