Purple bush beans are a variety of common garden beans known for their vibrant purple pods. These beans are typically short and compact, making them ideal for small gardens or containers. They grow on bushy plants that do not require staking, which simplifies their cultivation. The purple color of the pods is not just for aesthetics; it indicates the presence of anthocyanins, which are beneficial antioxidants. When cooked, the beans turn green, but they retain their nutritional value. Bush beans are generally easy to grow and can be harvested in about 50 to 60 days after planting.
