Larissa, some sellers on ebay sell fresh seeds, which I managed to get sprouted. I've had some success with especies-seeds.com (they sell on ebay too) and jungleseeds.co.uk but I've asked first if seeds I'm interested in are fresh or not and skip few which was stored for more than year.
BTW I'm also going to buy Ravenala madagascariensis so I may buy few from you if you don't mind or we can split expenses, if you find fresh one
jmore, if you don't mind send overseas, can you tell what fresh seeds you have in your stocks? I'm interested in hardy(maybe sikkimensis) or edible varieties in first place, as wish to try cultivate one in my garden and protect it in winter.
