Re: Musa balbisiana
None of these can ship to Norway without a phytosanitary certificate, since Norway is not a member of the EU.
Best thing would be to take with you 5 plants when visiting other countries.
Seeds offcourse, is no problem. You can get balbisiana seeds almost anywhere. I would have to say Trebrown has the best quality banana-seeds I have ever tried. My Musa Balbisiana seeds from there have started sprouting in just over 1 WEEK after sowing!!!
