‘Flageolet Vert’ was a new bush bean (Phaseolus vulgaris) variety for me in 2019. I can’t speak from personal experience about its edible qualities, as I was trying to save as much of the harvest as possible, but from what I have read, the small, pale green seeds are supposed to have outstanding flavor as a dried bean.

The plants are rather compact, and I suspect they would grow well in containers, which would make harvesting the pods easier. Full sun. Annual.
Harvested in August 2019. At least 15 seeds. I grow out only a few bean varieties each year, to avoid cross-pollination, and I did not grow this one in 2020. Once these sell out, I will not have a fresh crop until the fall of 2021.
