MJ, I did a little research on the T. simulate, aka "Broad Neddleleaf" and found out that though this plant is common it is found no where else in the US or in the world. How about that. It only grows in a few counties in FL but no where else. That would be a good plant to try my hand with if you can collect enough. A bonus would be any other plant (air plant) that you know is not the "Ball Moss", even if you don't know exactly what it/they are.
As you probably saw from the post by Tim in TX, "Ball Moss" might grow in two distinctive forms. It apparently grows differently in Texas than it does in Florida. This might make ID'ing some you see difficult, since, of the large batch I got from S. FL, some look like the TX form and some like the FL form. I know it will take some time to collect enough to fill a good size box (e.g. 12x12x12") with approximately 3 lbs, so if you are up to collecting a bunch for me, that would be great. There is no rush. I have plenty of orchids that I can trade and my orchids are not going anywhere.
