I made a quick trip to the Hill this evening to pick drying bean pods - blauhilde, triomphe de farcy & bird's egg (or were they climbing barlotti...?)
Although I was quite sensible in planting total different varieties side by side down each side of the bean frame, so I could easily tell which variety is which, I wasn't quite so clever in making sure that totally different varieties were grown opposite each other.
Some of the beans sneaked up their opposite counterpart's poles - which is fine when you have two sets of beans like 'polish' (heavy black streaked pods) and 'pea bean' (greeny-yellow pod), as they are easy to tell apart when picking.
But if they are very similar varieties - like 'bird's egg' & 'climbing barlotti', well they are pretty indistinguishable inside and out. I can't be sure I've kept them separate so I've bunged them all in together.
They'll still taste as good, I'm sure, & if I do want 'proper' seed for next year I'll worry about it nearer the time - it's not like I'm short of varieties to try...
