Five of the best runner beans to grow

There's a wide range of runner bean to choose from - here are five of the best.

'Scarlet Emperor'

'Painted Lady'

Runner bean 'Painted Lady' is a Victorian variety that is grown as much for its pretty bicoloured red and white flowers as for its large crops of tender, medium length, well-flavoured beans.

'Red Rum'

Runner bean 'Red Rum' is a self-fertile, which means that it doesn't need cross pollination from other bean plants nearby. So even if you grew one plant, you would enjoy a tasty crop. 'Red Rum' starts cropping early in summer and carries on producing heavy crops of medium-length beans throughout the season. Its ability to set beans even in poor weather means it outcrops many other varieties.

'White Lady'

Runner bean 'White Lady' bears pretty, pure white flowers and long, mid-green, stringless, tender pods with white seeds. It's a reliable and heavy cropper, and is more tolerant of dry, hot conditions than some other varieties.

'Polestar'

British bred, 'Polestar' is a is a reliable runner bean that bears heavy crops of stringless and smooth, fleshy pods. They have a good flavour. It's early to flower and the flowers set easily; it crops over a long season.

Try growing sweet peas alongside your runner beans - not only does the combination look pretty, it will help to attract beneficial pollinators, too.

Tips for growing runner beans

• Sow seeds under cover from mid-April and plant out from late May.
• Alternatively sow in mid- to late May, outdoors. Sow two per support.
• Grow in a sheltered, sunny position and dig in plenty of organic matter into the soil before planting.
• Protect seedlings from slugs and squash blackfly as soon as they appear on shoot tips.
• Keep plants well-watered.
• Pick beans regularly, as leaving pods on the plant will stop production and shorten the season.
