Holy..........(cow)!
I don't think you realize what you've got. "Pisang Ambon" is THE holy grail in my opinion of the Gros Michel varieties. I had told Tog Tan about this one and he searched for months before he found one. Treat it like gold and go the extra mile by giving it the best soil mix and largest pot , most light/heat and fertilize appropriately.
On second thought , go back to my first post send to: Bob morris plains nj ......etc
Boy am I jealous..........please keep posting pics of it's progress,
CONGRATULATIONS
