Either "Grandma Roberts" (round podded) or a flat-podded variety from SSE just named "Czechoslovakian". Both are completely purple, yield heavily, and tolerate some heat; but of the two, Czechoslovakian has been more dependable under trying conditions.
"Blue Marbutt" has round, purple-blushed pods, black seeds, and a somewhat late but heavy yield over a long period.
I've grown "Trionfo Violetto" and "Kew Blue", both of which are flat-podded and very similar. Good flavor, but I was disappointed in their yield.
