Guide to Growing Runner Bean, Lima Bean and other Common Beans

Phaseolus plants are vines that may reach from 60 cm to 1.8 m.

There are many varieties and they may be grown as half hardy annuals, hardy annuals, or hardy perennials in the garden.

They bloom in the summer, usually with red or white papery flowers.

They then produce bean pods, these should be harvested for eating when they are about 10 cm long.

Some common names for Phaseolus include Runner Bean, Snail Flower, Lima bean, Butter bean, White dutch runner bean, and corkscrew runner bean.

How to Grow Runner Beans (Phaseolus)

Seeds of Runner bean, Lima Bean, and other Phaseolus plants should be sown eye down in spring about two weeks after the last frost. They should be sown at about 2.5 to 3 cm deep into a sunny part of the garden. Once growing Phaseolus members such as runner bean should be provided with a trellis to grow on. Ideally the soil should be rich and moist.

If starting runner beans off indoors start about 5 weeks before due to be transplanted outdoors in mid spring. The beans should first be treated with an inoculate and sown eye down into peat pots. It should take about 5 days for the runner beans to germinate at 15 to 21 degrees centigrade.
