After many years of trying, I managed to get a decent crop of dried runner beans / løpebønner* (Phaseolus coccineus). My own garden is a bit too cold due to the shady conditions on a rather windy spot. Last year I grew a selection of 15-20 early varieties sourced from the German gene bank IPK Gatersleben and commercial suppliers which I grew successfully in the sunnier community garden (Væres Venner).
They were made into delicious falafels,  accompanied by living room grown Kandahar cress (karse) and wild buckwheat / vill bokhvete and turned into gourmet food with a couple of dandelion flowers from the windowsill! 
*In Norwegian, these beans are known usually as blomsterbønner (flower beans) and most often used as an ornamental. I prefer to call them løpebønner to better reflect that these are much more than an ornamental!
