Blue lake beans come in either bush or pole varieties, and I'll bet the seeds look exactly alike- small, kidney-shaped white beans. There might be a semi-twining blue lake variety as well, but I wouldn't know.
However, looking at the seed you couldn't tell.
Certainly a few could get sprinkled from one bin to another.... especially if the same scoop is used on multiple bins.
