When you have such a lot, you can afford to experiment. My filifera survived outside only due to protection I gave it. We had an awful winter here and it still lasts - worst since 1985 (we've beaten you, he-he

). This year I'm intended to try s. minor and r. hystix outside, if i find a decent place for them.
As for getting past the Schengen zone - thanks for the offer, there's few scenarios - we can believe the b*****it current Ukrainian "President" says (moos, to be more precise) and wait one year for the visas and all that stuff to be cancelled and still get nothing because it's science fiction.
And the other way is I can ask for the help of my bamboo-nut pal, who lives on Slovak border in Uzhhorod

I guess he has some experience in this area
