What to Eat
Edible parts: Seeds, Pods, Leaves, Roots, Vegetable, Flowers
Immature seedpods can be eaten raw or cooked — they have a pleasant, mild flavour and are widely used as a vegetable around the world, whether added to salads, cooked on their own, or included in soups and stews. Immature seeds are used as shelled beans. The protein-rich mature seeds can be dried and stored; they must be thoroughly cooked before eating to destroy a toxic principle, and are best soaked for 12 hours prior to use, then boiled or added to soups. The seed can also be ground into a powder and mixed with cereal flour to make protein-enriched bread. Flowers are edible raw and have a bean-like taste. Young leaves can be cooked and used as a potherb. The root is starchy and can be cooked, though one source notes it may be poisonous.
Known Hazards
Where to Find It
A tropical plant. It grows naturally in the mountain regions from Mexico to Panama. It is grown in the highlands in the tropics. On the tropical coast seedlings die and pods are not formed. It is damaged by frost. It suits hardiness zones 8-10. In Sichuan and Yunnan.

How to Identify
A climbing bean. It is a robust plant and keeps growing from year to year by re-growing from the fattened root. The stems are often hairy. It grows 1.8-2.4 m high. It can spread 1.8-2.4 m wide. It twines around a trellis. The leaves are compound and have three leaflets. The flowers are bright red. They are in clusters 2.5 cm long. The pods are long (30 cm) and with a wavy edge. The seeds are large and can be several different colours. It sometimes has a root tuber.

How to Grow
Requires a warm sheltered sunny position in a rich well-drained soil with plenty of moisture in the growing season. Dislikes heavy, wet or acid soils. Prefers a pH in the range 6 to 7. The runner bean is commonly cultivated in many parts of the world for its edible seeds and immature seedpods, there are many named varieties. Most varieties are climbing plants but some dwarf forms have been developed. Plants are perennials but are often grown as annuals, especially in the temperate zone. Plants flower under long day conditions, which is ideal for temperate regions. When grown for their edible pods, the immature pods should be harvested regularly in order to promote extra flower production and therefore higher yields. The perennial roots will survive mild winters outdoors in many parts of the country, especially if given a protective mulch in late autumn, they will then give an earlier but lighter crop the following year. They can also be dug up in late autumn and stored like dahlias in a cool but frost free place over winter and replanted in the following spring. The plants might need some protection from slugs since these creatures adore the young shoots in the spring. Runner beans grow well with carrots, cauliflowers, cucumbers, cabbage, leek and celeriac. They are inhibited by alliums and fennel growing nearby. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby. Carbon Farming - Cultivation: regional crop. Management: standard. Phaseolus coccineus ssp.polyanthus (Cache Bean) is also worth considering as a carbon farming plant. It is similar to Phaseolus coccineus but more suited to tropical highlands and semi-arid conditions.
Propagation: Pre-soak the seed for 12 hours in warm water, then sow in mid-spring in a greenhouse. Germination should occur within 10 days. Prick seedlings out into individual pots when large enough to handle, and plant out after the last expected frosts. Seed can also be sown in situ in late spring, though it may not ripen in a cool summer.
Medicinal Uses
None known
Other Uses
The plant fixes nitrogen. It also attracts hummingbirds.
