@Bluejay77 wow, so many segregations from the beans you grow. I've only had this happen once in all the years I've been growing beans. Here's my one and only.
I've been growing this bean since the 70's early 80's? I'd have to look it up. Back in 2010 I grew a teepee of Mr. Tung's a pole bean brought to Canada well over 100 years ago now. I was given a sample of this bean by the granddaughter of the family who originally grew it.

Mr. Tung and the seed it produces.
In one pod there was one seed that was a different color.

The one different colored seed and the pods it produced when grown. I grew seed from one of these pods the next year and got this....

Shelly and dried seed, I grew a few seeds from this and got this...

Pod with more pink and again a different shaped seed and a different colored seed coat.
I think I have a few of these seeds still kicking around somewhere but doubt if I'll grow it again. I was only growing one other bean that year but the teepee wasn't anywhere near this one so pretty sure it wasn't a cross.
For many years aside from scarlet runners I only grew two varieties of common beans, Mr.
Tung's and an Italian pole bean brought to Vancouver Island from Italy in the early 1900's.
I got my seed for Mr. Tung's from the woman who wrote the below article for the now defunct Island Grower. The Italian pole bean ( Emilia's Italian ) is another story, in fact in was my quest in finding out the history of this particular bean that started my heirloom bean collecting addiction

Mrs. Mollison has since passed away but being the pack rat that I am I kept this article. Low and behold the daughter of Mrs. Mollison found a few of these beans when going through her mother's things and started inquiring if anyone had a copy of the article she knew her mother had written about them. She found it at the Populuxe Seed Bank, I had sent it to the PSB a year or two before as the information they had on it wasn't quite accurate. (Note to self, no matter what DH says never throw anything away, it might be important some day).
I sent some seed to Remy (Sample Seed Shop) a couple of years ago, she had it listed in here 2016 catalog.
I also got my first Cherokee Trail of Tears beans from an offer in the Island Grower back in the 80's and have been growing these also since then, not every year as I have so many varieties in my stash I haven't grown yet. I try hard not to add to my bean stash but have to admit I'm failing miserably.
It's the history that goes with these family heirlooms that absolutely fascinates me, the so sad story that goes with the Cherokee Trail of Tears is a reminder that we have come a long way since then, we still have a long way to go, but we're getting there.
I'll start another thread about Emilia's Italian, it shows how important it is to some that these heirlooms are kept in circulation, sharing with as many others as you keeps them from going the way of the Dodo bird.
