Begonia rex is part of the Begoniaceae family and its native range is Bhutan to N. Myanmar. It is a rhizomatous geophyte and which grows primarily in the subtropical biome. It was first discovered in Assam (India) and introduced into cultivation in the 1850s. It has been used prominently in hybridising, giving a huge number of cultivars that boosted foliage Begonias as indoor plants.
This cultivar is showy and compact with spiral leaves and ruffled/toothed leaf margins and dark edges.
The genus name honours Michael Begon (1638-1710), a patron of Botany.
Light: Bright indirect light, meaning the plant sees the sun for 0-4 hours per day - this could be through trees or a translucent curtain, it’s important for the plant to see the sky in order to thrive.
Water: Given adequate light and a well draining potting mix, Begonia prefer mix to be evenly moist. If the mix is heavier, allow the pot to get lighter in weight and at least 50% of the potting mix to dry out.
Potting mix: A rich well draining mix composed of coco coir, perlite or vermiculite, orchid bark and worm castings. Adding horticultural grit or sand is also a good amendment to increase drainage.
Fertilising: Feed your plant every other watering during the growing season or when you observe active growth. You can dilute the fertilizer to half the recommended amount but never add more.
Temperature: Day time 19-21˚C, night time 16˚C.
Humidity: Begonia rex prefer humidity of 60% and above with good airflow.
Begonia are toxic, keep out of reach of pets and children.
