Huh. I could probably do that.. Begin with reading books about meteorology, starting with general introductions and branching into microclimate, then geology and geography, again introductions first and then more detailed works about the climate zone you're interested in. You should be able to get books about smaller regions, continents is easy, many countries can be done. And of course, you'll need information about the plants you're looking for - what kinds of water, light, nutrients is best and what is permissable, deduce from this the possible places and the plants that should go with it. Could also help to look at pests the plant is susceptible to.
If you need more details, you can get into the recent literature which might not have made it into a book yet or which is not part of a big-enough field. You should be able to understand most by now; refer back to the books if there are issues.
Any university library should be able to offer these; if you buy it'll easily be a few hundred since one book can cost over 150€. So there.
Edit: Once you get enough into the details, it's also a good idea to start asking people. (And the way your comment's parent put it, there should be a community around who has very detailed knowledge about these things. Befriending them would help. Or try to shoot an email to any professor, most of them are very open to reasonable enquieries (which are not demands to prove your perpetuum mobile idea please.. some people..) But then again, how far do you want to go?)
