Hello,
I live in Northwestern germany, and I am a perfect beginner with tropical looking plants. Some websites, including this one, finished to convince me that an exotic garden may be possible in my place!

So I'd like to ask a few questions (pardon my English, which is not always top-level) regarding my little project. I have not an extended knowledge of tropical-looking plants. That's the first trick!
Could you "introduce" me with the easiest tropical-looking plants that you know? Also, they should be fairly hardy. Water is not a problem here, I can manually and automatically water, if needed.
Any suggestion?
Many thanks in advance, MirandaPn.
