Pea beans

I grew YinYang and Inca Pea bean last year, the beans do look similar although Inca is more of a reddish purple whereas YinYang is black.
The plants are different though YingYang is a dwarf French bean as Scarlet says but Inca grows to about 5 ft and the pods form a bit differently to any CFB I've grown, the link you sent of Jack Edwards says lumpy and that's about right so I think Jack Edwards and Inca may be the same fella or certainly a similar strain.
       

Always happy to have more seeds Veggie I think we all share the seed hoarding trait
I saved seeds this year mainly toms and beans previously donated by Scarlet and NG (thank you again ladies) as I want to keep the lines going but I didn't save with the intention of swapping so doubt I will have enough to go round everyone in the swap sadly. Also I wouldn't want to hold it up while I start bagging but I'll happily join any swaps going on this year.
