Well, that gives me some hope for my ensete 'Kluay Pa' seeds! I've been waiting for almost 18 months now also. Was your batch from RPS? Just goes to show, never give up on seeds unless they are obviously rotten. My m. ingens seeds still look good. I even cut a couple of them open, and both appeared to still be viable (still white inside). I had two trachycarpus takil seeds sprout after 17 months this Spring.
I've never ordered from Trebrown. How's their service and quality? What other sources do you use to order banana seeds? So far, I know of:
rarepalmseeds.com
banana-tree.com
europalms.be
trebrown.com
seedrack.com (a few)
seedman.com (never ordered from them, but huge selection)
jungleseeds.co.uk (never ordered)
ortanique.com
I purposely left gingerwoodnursery.com off that list...Tim Chapman has dissapeared into thin air, and I lost $20 ordering seeds from there in January
