As with a lot of Begonia cultivars it’s hard to find accurate information of their parentage due to the commercial names used. This is a cane Begonia with large angel wing leaves, the metallic green leaf surface is covered in tiny hairs.
Genus name honours French administrator and amateur botanist Michel Bégon (1638–1710) who discovered the plant on the island of Santo Domingo. Cultivar name means Great Grandmother in Danish.
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. An east-facing window would be ideal.
Water: Given adequate light and a well draining potting mix, Begonia prefer mix to be evenly moist. Try to keep water off the leaves.
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 fertiliser to half the recommended amount but never add more.
Temperature: 16-29˚C, the middle to lower end of this range is thought to be the best.
Humidity: Begonia prefer humidity of 60% and above but adapt well to home conditions.
Begonia are toxic, keep out of reach of pets and children.
