Here are the f3 of a cross that showed up a few years back. I was initially a bit disappointed with the f2 (last year) because they didn't flush with a purple haze as nicely as the f1. Also the beans were rather short. On the other hand they are really delicious and have very decent anthracnose resistance. I believe them to be a cross between Anellino Giallo (Anellino Yellow) and Cherokee Trail of Tears. (No, not all my bean crosses are fathered by CTOT, just 95% of them.)
I'm actually seeing more variation in them this year; some of them flush purple more quickly than others, and some of them are quite long while others are still fairly short. I know some of them have strings and some of them don't and I need to work on getting that out. We also have yellow mosaic virus in the beans this year, quite badly, and there is variation in how well they are handling that.
I'm quite hopeful that another few years of selection will make these a distinctive and rather special bean.
