Begonia Miri Sarawak Borneo Sp. Care

ABOUT 
Unfortunately, not too much is known about the Begonia Sp. Miri from Sarawak (a Malaysian state on the island of Borneo.) What I can tell you is that it is a cane Begonia with a vertical growth habit and is considered a terrarium plant. It requires a high humidity environment (such as, you guessed it - a terrarium, greenhouse, cabinet or other enclosed container) and would not survive in normal household conditions. 

FAMILY 
Begoniaceae

LIGHT REQUIREMENTS

Moderate to semi-shade. 

TEMP / HUMIDITY 
70 - 80° F (21 - 26.5° C) / 75% + Humidity.

WATERING 

Keep soil evenly moist but not waterlogged. 

GROW MEDIA 
These guys don't seem very particular about their substrate, at least in my experience. I have grown them in perlite and Pon, as well as in a more standard coir (or soil) based substrate (something like a 70/30 mix, or a 1-1-1 coir (soil) to perlite to coco husk or orchid bark would be fine.) 

I haven't tried to grow them in LECA, but I suspect they'd do alright. They have a root structure similar to most other cane Begonia, and I've had no problems with those in a chunkier media. 

GROWTH RATE 

Provided they're getting enough humidity, I've actually found them to be pretty fast growers. 

EASE OF PROPAGATION 
On a scale of 1 (easiest) to 5 (most difficult) I'd say... 3. They can be a little challenging for people who are new to propagating these kinds of plants, but for anyone experienced with more sensitive Begonia, they should be relatively hassle-free.

TOXICITY 
I have absolutely no idea. So I would definitely err on the side of assuming they are toxic to pets and humans.

ADDITIONAL INFO 
None at this time.
