First off, welcome to bananas.org! I hope you enjoy it here and learn a lot about banana cultivation. The people here are great, so if you have other questions, just ask! I wish you the best of luck in your quest for the Pisang Kates. I've never heard of it. I'm sure if Tog were still around he'd probably know just how to get a hold of one....
Well, keep searching! We'll help in any way we can!
