some kind of bean?
Your plant is clearly a green, snap or some variety of garden bean. As to which type or cultivar of bean, I dare not guess. You could probably sit down with any seed catalog and find a cultivar that resembles your green bean plant.
The problem is bean plant ID is that common bean, Phaseolus vulgaris, is a highly variable species. All varieties bear alternate, green or sometimes purple leaves which are divided into three oval, smooth-edged leaflets. The white, pink, or purple flowers give way to pods 3–8 inches long. These pods may be green, yellow, black, or purple in color. Each pod contains 4–6 beans.
On one hand, it might be frustrating trying to find the exact cultivar of bean. On the other hand, it might be fun to experiment with all that bean diversity to find the cultivar that best matches your tastes. Good luck in you endeavors.
