I've not had a great success this year with my seed saving as two trips and two invasions by mice have seriously depleted what stocks I had. Following recent advice, my seeds have all now been moved to better storage jars or boxes of either heavy plastic or preferably, glass.
However, one of the things I was successful with last year was the Poletschka bean. A purple pole bean, which has a beautiful small variegated bean. I don't really know whether I can call a bean variegated... but I'm sure you'll all know what I mean. I originally got the beans from Miss Fuggles at A blog called Fuggles, and grew them here for the first time last year. They were very successful.
I'm just sowing these now and it's a little bit late but if anyone would like to try them then I have a few beans I could let you have. Sadly, the offer can only be made to those people resident in Europe as the problems of shipping seeds beyond our borders is simply too complicated.
If you're interested, please leave a comment here or better still, email me.
