Oh ok. I know for sure polysperma is Hygro. From the structure of of the Ceylon, I assumed it to be Hygro as well. Maybe it is a Hydro. I believe hydro and hygro are two different things. If the Ceylon is trully a hydro, then no it's not illegal to sell.
But I believe any Hygro is illegal to sell. That was what i have been told, but I could be wrong.
Don't forget H. lacustris and H. 'Pantanal wavy" :wink: . I'm sure there are dozens of others not mentioned...
I'm not positive, but I think they use "Nomaphila" as the other genus name to avoid setting off alarms with "the powers that be." The LFS I get plants from works very closely with these "powers" and gets in many species of Hygros. AFAIK, only H. polysperma and its variations are illegal in the state AND illegal to import internationally no matter what state you're in. In fact, I think polysperma is banned from being sold anywhere, which is why it's almost impossible to find it on-line, even.
But no, there is no ban on all hygros. Not by a long shot... Thank goodness .
