The plan is to grow these outside, but also to get some of the smaller seeded bush lima, grow them in pots in the greenhouse if it's a bad summer, or transplant them outside if it's a good one like 2006 (if good was the word).

It may be that they're too much trouble, with no benefit over the beans we usually grow
