Blooming Prairie does look like one of the Robert Lobitz beans that I've grown here. yes, a pretty bean. nice plump ones he can grow.

i've tried to get ahold of a grow all of the RL purple beans that look like BP (sourced from
@Blue-Jay). i'm not sure if i've missed any.
i've done my best to distribute them in my area and at any seed swaps i've been to and sending them to a few people via the mail. i think i've probably given away at least a thousand samples (of just Purple Dove) along with other beans that people have wanted from me over the past five years at seed swaps, but i've also been sending some beans around from my first few years of gardening.
