Its very interesting that the "ice cream" banana got this reputation for being so crazy awesome. It taste like Ice cream!
When in fact it is a banana that is far from the best, and is not the most productive or easy.
NOW HERE IS THE TRUTH!
The nam wah is THE TURE ICE CREAM! People just made the mistake of thinking the blue java is a nam wah.
Problem solved!
But in seriousness; if you want a good tasting, fast fruiting(ripening) banana that is care free, and More COLD TOLERANT than a blue java... You want a good Nam wah variety.
Its nothing to get a nam wah to fruit in a year, they don't need support either.
The only thing with the Nam wah is that there are quite a few mutations around. With all the tissue culturing you do have a few subpar ones getting passed around; small bunches, low vigor.....
But if you find someone with a good line you should not pass on a sucker.
