Saving BJBB seed
I hope this isn't too ignorant of a question... For most of the season, the only butter bean/lima type bean I've been growing was the Black Jungle Butter Beans. (now have some Fordhook Limas starting to flower) I have lots of pole and bush beans growing nearby the BJBBs.
I wanted to ask - are the BJBBs that have already dried in the pods likely to be "pure" seeds? In other words, could they cross with pole or bush type beans? I know there's some chance of crossing with the limas - but pods that have dry or nearly dry seeds now wouldn't have had limas flowering at the same time. I intend to bag some flowers for future seed saving - but too busy harvesting and putting up veggies.
I know I need to do the research, but time...
Thanks in advance for advice!
