I do volunteerwork in a kind of zoo here in the Netherlands, and we have a big greenhouse with tropical plants and animals there.
There are some bananas there, looking very much like basjoo, but how can I be sure?
I'll take some pictures soon.
They flower every now and then, but (although birds might pollinate it) no seeds in the small yellow banana's yet... I'll try to hand-pollinate them when I get the chance.
Would anyone (Mrbungalow?) be able to positively identify basjoo from a picture (flower, stem, leves, whatever you want) growing in the heated greenhouse year-round?
