That plant seems difficult to be made happy. I never knew they are bog plant. interesting.
Perhaps that's why it is difficult, because we did not gave them their proper environtment.
I'm not sure that my growing style will give you any idea. I found that some of those difficult plant seems grow better in companion of other plants.
I grow this, in a hanging pot, using forest humus as medium, together with Scindapsus geesinkii, and arisaema filliformis, all three are difficult for me, but seems they grow little better in group. it is not happy yet but at least it still survive.
The grouping seems making microclimate suitable for them, both in air humidity and growing medium zone.
May be you can grow them in terrarium with multiple plants. Too bad, not much information on the net of their culture.
