Has anyone raised fava beans?

[Aunt Bean]

Hi first time I've seen this part of neurotalk...pretty cool! Has anyone raised fava beans? Our favas made it daown to 24 degrees and then got bit. I saw on some site that the plants will start to grow from the roots again when it warms up alittle. I just don't know wether to leave the slumped over plants there or cut them off some. I am leaning toward leaving the whole thing there...just in case the cold rain/snow would go down inside the stems and damage the root. Anyone have experience with this? Please write me a personal message. Thanks Aunt Bean
