A co-worker just gave me a bag of seeds from her Scarlet Runner Bean. She said they are a couple years old. I'd be happy to send you some if you're still interested.
I have Blue Bean seeds ( decaisnea fargesii). They are from 2011, but at least half of them will sprout. I have 10 seeds left from last year & will send you 5 of them, if you're interested. No postage necessary; just PM me with your addy if you want them. Happy gardening!
