Scarlet Runner Bean
The Scarlet Runner Bean (Phaseolus coccineus) is a perennial climbing bean known for its striking scarlet flowers and large edible seeds, valued both as an ornamental plant and a food crop especially in temperate regions.
Origin Story
Native to the highlands of Central America, particularly southern Mexico and Guatemala, the Scarlet Runner Bean was domesticated by indigenous peoples before European contact. It was cultivated for both its nutritional seeds and vibrant flowers. The species was introduced to Europe in the 17th century, where it diversified into numerous horticultural varieties selected for flower color, seed size, and cold tolerance.
Classification
The Scarlet Runner Bean belongs to the Fabaceae family, genus Phaseolus, and species coccineus. It is part of the pole bean group, distinguished from the common bean (Phaseolus vulgaris) by its perennial climbing habit and greater cold tolerance.
Appearance or Form
This vigorous, twining vine can grow between 2 to 4 meters tall, producing long pods up to 30 centimeters in length. Its flowers are bright scarlet, occasionally white or bicolor, making it visually striking. The seeds are large, kidney-shaped, and typically purple-black with mottled patterns.
Behavior or Usage
The Scarlet Runner Bean serves a dual purpose: it is grown both for its ornamental flowers and its edible pods and seeds. The immature pods are eaten fresh as snap beans, while mature seeds are consumed fresh or dried. The plant tolerates cooler soils better than many other beans, making it suitable for temperate climates. However, the beans must be cooked thoroughly to neutralize natural toxins.

Specific breeders or release dates are not well documented, reflecting the bean's long history of indigenous cultivation and gradual horticultural development.
👩🌾Cultivation Tips
Scarlet Runner Beans thrive in temperate climates with cooler soils where other beans may struggle. They require sturdy supports for their vigorous climbing habit and benefit from well-drained soil rich in organic matter. To maximize yield and plant health, monitor for aphids, bean beetles, and fungal diseases. Harvest pods when young for snap beans or allow seeds to mature fully for drying. Proper drying is essential to preserve seeds for storage.
🛢️Storage And Preservation
Seeds and mature pods of the Scarlet Runner Bean should be thoroughly dried before storage to prevent spoilage. Fresh pods are best consumed soon after harvest. Properly dried seeds can be stored in cool, dry conditions to maintain viability and quality. Cooking is necessary before eating to eliminate natural toxins present in the beans.
