@needrain Can you take a picture? 10-15 inches is the size I have depending on how harsh of a spot I put them in. I went Topaz hunting in Mason and came across a large sized grouping of these in the same kind of outcropping you are talking about by a river bed. I dug up very carefully a very small portion to take home and it did not make it. I felt awful and should have left them alone. But..... I also found some on a rock cliff in full sun on my way through Llano and brought some home and it did great. If you do decide to try relocating some just take a small amount and try to not disturb the roots of the ones you are leaving. I have tried this with maiden hair fern on our land in a seasonal creek bed with mixed results. Oh, that's another good one. Maiden Hair fern. Very pretty too! The root systems can go very deep and wide in the limestone crevices for them to survive in such xeric conditions. I actually found some wavy cloak fern being sold at ACE hardware of all places.
