Tarzane Group recently listed five new Nervilia species and I'm taking the plunge and trying one of each. A couple of them are pretty slim in terms of available habitat data, so I'm trying to make determinations as to which will go in the greenhouse vs our cool case where we grow a number of pleuros and the like. Is anyone else trying these fascinating little guys?
One of the things that I do when I get plants from Tarzane Group, if they don't have a culture sheet in that area, is to copy the information from each one - because once it's sold out that page (with its very useful information) goes away.
I can't help you on the details, haven't grown them. You might also email Tomas ... he is extremely responsive to questions. Since these are species without a lot of information, you'll need to grab info wherever you can find it...and the sum may give you the guidance that you need.
