Thank you, Tofi. You have given me much food for thought! The plant is in what appears to be chopped spaghnum. When it comes time to pot up, I plan to use the 1-1-1 moss mix I use for cuttings … equal parts chopped long-fiber spaghnum, chopped sheet moss and peat. To provide bog-like conditions, the pot is sitting in a saucer with a half-inch or so of water. My plant room runs 65-80% humidity but I put the plant in isolation in a 2-gal glass jar. So far, so good.
I'm thinking of putting it in a 20-gal aquarium set on end with a piece of acrylic covering the open side. Given your idea of providing companions, I'm thinking I'll put Anthurium cutucuense with it — the aquarium on end should be tall enough to give A. cutucuense some room to grow. Do you know how big the chlorospatha will get? Also, is it a climbing plant? ie, should I provide it a pole to climb on? Thanks so much for your help?!
