Hi Forester!
I think those topics might be too narrow to support an entire forum. Your best bet is a place like this, with lots of people who have lots of knowledge.
The plants you mentioned will be quite a challenge in Riussia. I grow both of these in my greenhouse, and they can be tempermental to say the least!
If you have specific questions or comments, post them and see what responses you get.
Good luck!
Carolyn
