Facts about Scarlet Runner Beans

Unlike common beans, the plant is a perennial vine with tuberous roots, though not typically treated as such within agricultural methods and cycles. There are nearly twenty different cultivars (man-made types) of Scarlet runner bean, and all are known for the colorful seeds the pods produce. True to their name they are first and foremost known for their bright scarlet blooms, so much that in most seed catalogs they are listed under “ornamental”, “flowers”, or “hummingbird plants” rather than “beans.” Today the Scarlet runner is mainly grown as an ornamental in the United States though it is available when in season from local farmers markets. In Europe runner types such as the Scarlet have long been a popular edible bean both whole in their immature form and when mature and shelled for their edible seeds.

Plant Description

Scarlet runner bean is a climbing (vining), tuberous perennial or a bushy, annual herb that grows up to 3 m (9 ft.) or more in length. The plant is found growing in or around mostly mixed forests, often on steep slopes or along stream beds, open wooded grassy areas, or on edges of cloud forest. The plant prefers warm sheltered sunny position with a consistently moist, fertile, organically rich well-drained soil with plenty of moisture in the growing season and normally dislikes heavy, wet or acid soils. Leaves of Scarlet runner bean are trifoliate and all the leaflets are broadly oval, measuring anything between 10 cm and 12.7 cm in length. Most varieties have red flowers and multicolored seeds (though some have white flowers and white seeds), and they are often grown as ornamental plants.

Flower

Flowers in most cultivars are bright scarlet red, and shaped like typical bean family flowers with the two lowermost petals united into a keel, the uppermost petal modified into a hood like standard, and the lateral petals modified into spreading wings. The flowers are about an inch long and clustered on many-flowered racemes up to 10 inches long. There can be as many as 20 flowers on a single flowering stalk. Flowering usually takes place from July to September.

Fruits

Fertile flowers are followed by linear-lanceolate, straight or slightly curved pods that are 9–30 cm long and 1.5–2.5 cm wide, laterally compressed, beaked, glabrescent, and rough with small oblique ridges, 3-10 seeded. Seeds are ellipsoid-oblong, 13–25 mm long and 6–13 mm wide, black, white, cream or brown, often pink to purple mottled.  The green pods are edible whole but in some varieties (the scarlet runner) tend to become fibrous early, and only the seeds within are eaten. The seeds can be used fresh or as dried beans. The starchy roots are still eaten by Central American Indians.

Beans are delicious when young, but if left on the vine will eventually develop into large tough pods to 1.5 feet long. Runner bean is basically the same thing as a pole bean (American term) in that both do basically the same thing, namely, climb and produce edible beans. Runner beans produce flowers about 4-5 weeks after planting of the seed, with first harvest in 60-75 days. Picking the beans encourages production of additional flowers.

In addition to being handsome ornamental climbers, runner beans also attract hummingbirds, butterflies and bees. Runner beans twine clockwise whereas most other types of beans twine counterclockwise.

History

Scarlet runner bean occurs wild from Mexico to Panama. It was probably domesticated in Mexico. Archaeological evidence shows that scarlet runner bean was a domesticated crop in Mexico around 900 AD. Nowadays scarlet runner bean is cultivated in temperate countries and occasionally in highland areas of Central and South America, Africa (e.g. Ethiopia, Kenya, Uganda, and South Africa) and Asia. It is probably cultivated in Madagascar and is recorded as being grown in the eastern part of tropical southern Africa, although no specific countries are mentioned.

Scarlet runner beans with Chili Sauce

Ingredients

• 1 pound dried scarlet runner beans
• 4 ancho chilies, stemmed and seeded
• 1 onion, quartered
• 3 garlic cloves
• 1 cup chicken broth or water
• 1 teaspoon cumin seeds, toasted and ground
• salt and freshly ground black pepper to taste
• crumbled queso fresco or feta for garnish
• chopped fresh cilantro for garnish
• lime wedges for garnish

Directions

1. Place the beans in a large bowl and cover with at least one inch of water; let soak overnight.
2. Add the beans and their soaking water to a large pot. The beans will have expanded, so make sure they are still covered by at least an inch, maybe a bit more.  Turn your heat to medium high and bring to a hard boil.
3. Keep the beans at a boil for about five minutes and then reduce them to a gentle simmer, then cover. When the beans are almost ready, the aroma will be heady. If the bean water starts to get low, always add hot water from a tea kettle.
4. Meanwhile put the chilies in a small bowl, add hot water to cover, and soak until soft, about 15 minutes. Drain the chilies and put them in a blender with the onion and garlic. 
5. Purée until smooth, adding some chicken broth or water to thin the mixture if necessary, the texture should be like a pourable pesto. You should have about 1 1/2 cups of chili purée.
6. In a small, heavy skillet over medium-low heat, cook the purée, stirring occasionally, until the bitter flavor begins to mellow, about 15 minutes. Add the cumin and salt and pepper to taste and cook for 10 minutes to blend flavors.
7. When the beans are beginning to soften, after about one hour, add the chili purée and season the whole mix with salt and pepper. Continue cooking until the beans reach the desired texture, depending on their age, another 15-45 minutes.
8. Serve as a vegetarian main dish or as a super healthy side topped with queso fresco, chopped cilantro and a spritz of lime.
