Hi Olivier,
Thanks very much for your reply. I really think we have a match in the plant you describe. That's why at first I thought it was some sort of Musa.
I myself was also very surprised that these seeds were still viable. Only 3 of them germinated, but really fast within 2 weeks. Untill today I had them outside here in Belgium, and allthough temperatures were not that warm the plants kept making new leaves. So somewhat lower temperatures are not that bad for them. But now we expect frostst, so I put them inside.
Is this a perennial or annual plant? I hope I can get it through winter without difficulties so next year growth can go on. These small plants already have strong rootgrowth in their pots.
Thanks very much for your support.
Gr. Albert
