Gardeners' Notes:

I had never grown lima beans, and my husband wasn't enthusiastic about eating them, but the description of these sounded so good that I took a chance on a packet. The vines grew to enormous size, with lots of pods, and the flavor converted my husband to a fan. It's a fair amount of work to open the pods, and there are just a few of the huge beans in each one, but they are worth the effort.
