Begonia montaniformis is another quite new-to-the-horticultural-scene, stunningly-beautiful species hailing from limestone areas in northern Vietnam, south of Hanoi. As it is quite new to cultivation, my experience growing it is so far limited. However, like others of its ilk, it has responded well for me using the almost-closed terrarium type culture that suits so many of the other rainforest understory species. The only exception is that I incorporate a roughly 5% ratio of limestone chips with my otherwise pro-mix based potting medium.
In its native habitat, it is described as being found in lowland forest on highly eroded limestone slopes & cliffs. I suspect it will be somewhat wet-sensitive - so keep that in mind. It should be understood that this may be a challenging species - time will tell.
The foliage of B. montaniformis is a wonderful mix of densely packed raised black (melano) cones (bullae) (though much less pronounced than B. ferox or B. melanobullata) and with significant silvering along the veins/valleys.
Offered here as husky young plant in 2 1/2" - 3" CLAY pot. Note: these are slow to mature/develop so represent a year or more worth of very careful culture to get to this size.
