I would like to plant a nice three sister style garden this year, but since I would need a lot of beans to partner with all the corn I was planning to plant I was thinking of buying dried beans from the grocery store and planting those.

I have heard that mass producers have bred beans that are normally pole beans into bush beans...

if this is true I would like to know which beans (from the supermarket; I shop at whole foods/stop and shop) grow to be pole beans; as those are the ones necessary for a three sister garden.
