Local runner bean landrace

I’ve started work on a local landrace of runner beans / blomsterbønner (Phaseolus coccineus). I sowed yesterday 15 varieties that are the earliest varieties I could find from commercial suppliers and the German genebank IPK Gatersleben! Runner beans are marginal here, only ripening with warm frost-free autumn weather, preferably against a warm south facing wall!
Thanks to Raphael Maier who told me that the IPK Gatersleben have phenological data for part of their collection of over 400 runner beans. I therefore looked for early flowering and early ripening data when selecting varieties.
The assumption is that it will eventually get warm enough to plant them outside at the community garden Væres Venner where I will run the trial! Currently still only maximum 8C and the 10 day forecast shows much of the same with low pressure dominated weather and only a slight increase to 10C.
