What are the pros? Interesting bean
What are the cons? May be wrong type for US
While I have not as yet tried these rice beans, I DO have some experience with growing rice beans (using seed bought in Chinatown being sold for food.). Based on my experience and the picture, I think the problem may be that Joe got the wrong strain on his trip. There are a lot of strains out there, but they fall into two main groups. What seems to be here is the Southern strain, which is indeed too day length sensitive to flower and make seed for most of the US. But there is another strain, differing in average seed size (it's a bit bigger) and color (the red is lighter, more of a brick/hot dog color) that is somewhat more tolerant (I can get a crop off of that one here in NY so for most of the country, it would be easy.)
Not to disparage Joe's work, just a heads up should he be back in China hunting any time soon.
