available in the US are bell beans (a type of fava), Vicia faba which are cold hardy to -12C but some people have an intolerance to fava beans.
Hodmedods sells them as “Carlin peas” but there is no lowest growing temperature. They look like and are cooked like chickpeas but are unrelated. I think in most languages it’s referred to simply as winter pea.
Anyway, I’m looking for a distributor who could ship to the US and the pea has a definite cold tolerance to at least -10C.
Thank you! 💚💚💚
