Czar beans turned blue/black

[RandAParticipant]

I sowed some czar beans in the spring all white seed, then last week we harvested the beans and were very surprised that one plant produced beans that are beautiful dark blue/black colour, the same size and shape as the czar’s. Can anyone explain what might have happened, do they cross (but the only black seeded beans we have are are climbing French beans) all the other runners we grow are are Gigantes, Firestorm and Streamline and Prizewinners and none of those beans are black. Will they be safe to eat? I hope so.

Fascinating, must be cross pollination. Luckily Czar tends not to, mostly!
I would eat them, no risk that I can even imagine as long as boiled as usual, 10 min min.

Thanks Charles some of the colours are really beautiful and really deep dark blue, we will try them and see what they are like maybe we have discovered a new variety !!!!
