Begonia cavallyensis, an African epiphyte, here grown mounted in a carved tree fern pot, stuffed with long fiber New Zealand Sphagnum moss. Fishing line initially holds the moss in place. Roots soon allow its removal. The key to this species' happiness, I have found, is in giving roots an airy growing medium, never remaining wet for too long. For perspective, this tank is two feet tall. I have also grown this species in an open hocking jar, in a pint plastic strawberry basket (from the grocery store) filled with the same Sphagnum moss.
