I am converting a 55 gallon tank into a terrarium. the medium I am using is going to be, shredded coconut husk, orchid bark, sphagnum moss, and oak leaves. I have learned how to blend moss and butter milk with water in a blender and paint my cork bark and branches for my terrarium to grow moss. the plants I have now for the tank are ferns, an African violet, a polka dot plant, a purple waffle, arrowheads, and creeping Fig. I would love advice on some flowering plants perhaps miniatures for the terrarium.I understand that miniature orchids would be nice but they may be costly. Stepacarpus would be nice if they where miniature. But miniatures are hard to find. Any suggestions on flowering plants for the terrarium?
