Purple string beans, also known as purple beans or purple podded beans, are a unique variety of green beans. They stand out due to their vibrant purple color. Here are some fascinating facts about these colorful legumes.

  1. Purple string beans turn green when cooked. The heat breaks down the purple pigment, revealing the green chlorophyll underneath.

Growing Purple String Beans

Growing these beans is similar to growing regular green beans. However, there are some unique aspects to consider.

  1. They prefer warm soil. Plant them after the last frost when the soil temperature is at least 60°F (15°C).
