They're just as easy to grow as traditional runner beans but are left on the vine to fatten up the inner dried bean seeds.
Like all runners you will need to sow these indoors no more than three weeks before the last frost. Sow 2 inches deep in a 7cm pot. Once all risk of frost has past, harden off the beans by placing outside during the day and bringing in at night or placing in a cold frame and lifting the lid during the day. Plant out after a week. They will need a trellis or other support up to two meters high. You may need to tie them to the support at first but after that they should climb up themselves. Remove the tips once the beans have reached the top of the support. Keep well watered and in July mulch with compost.
