Hi Joanne. I am so glad I found this Thread. I was given some pink banana seeds last Fall. I have been putting off planting them because I didn't know what to do. I will now go forth and plant. : ) What size ziplock did you use, and what kind of potting mix (MG)?
I see you live in Canada zone 3. If I get these to germinate and grow I would be able to plant it outside in our zone 8. If I get more than one of them to germinate I can send one to you if you like. It can live in your greenhouse. : )
