Thank you for the comps.
The hypertufa is a cement like material that is used to make troughs and planters. The material is very light and as it gets wet it gets stronger. They are made as you see with the piece of hollow wood or a drift wood and with holes so you don't have to make them, and holes to hang it. I think the nice lady also does custom work.
To tie it i used regular string and one i used wire.
Lorraine: After i was done i realized that i should have put the phals in a different position, maybe i'll fix the big one because it has a deep crown the mini is ok, I think. What is monofilm?
I have a Rhynchostylis gigantea RED would that be a good plant to mound? If not any suggestions.
