The scarlet runner bean is a robust and vigorous long-blooming annual twiner with bright flowers (hence the name). It is ideal for creating green privacy screens, for greening , for greening gazebos, fences, carports and, of course, for house walls and balconies. Runner beans flower even in the coolest summers!
Scarlet Runner Bean / Runner Bean / Multiflora Bean / Butter Bean, lat.: Phaseolus coccineus / Phaseolus multiflorus
The runner bean favours a sunny to semi-shady, warm and sheltered location with deep, fresh, loose soil that is not too wet. Good water supply is a must, especially on dry and hot days and especially if the bean is planted in a pot or tub. Available as seed blends with different varieties and colours.
This robust and fast-growing twining climber from Mexico has been known in Europe since the 16th century. After soaking them in water overnight, the runner bean seeds can be sown in 3 - 5 cm deep holes after the ground is at a temperature of 10 degrees (beginning of May). If there are still night frosts, the seedlings need to be protected (with sheets/mulch/straw...). When planting a line, keep a distance of 25 to 30 between seeds. When sowing next to a stake or another standing trellis, put 4 -6 seeds into every plant-hole. In colder regions, you might want to pre-grow the plants inside from April on. Growth height is up to 3 - 4 metres, sometimes even 6 m, with dense, green foliage. Red, white, or bicoloured flowers bloom from June to September, with a strong contrast to the decorative foliage. The abundance of flowers cannot be disturbed by cool, rainy summers. Bean fruits are poisonous when raw; young beans are delicious when cooked.
The runner bean can be grown in the garden, on fences, or on trellises-- with vertical wire ropes, cords, poles/rods. To cover a facade with foliage, place the individual vertical axes at a distance of about 50 - 75 cm from each other. See the bottom of the page for a list of suitable wire rope trellis designs for runner beans. An easy, light, or medium design allows optimal development.
