Concador was my first really successful green bean. I had grown Purple and Golden teepee before but found they got chunky quite early, were often misshapen and their promised ability to hold the beans above the foliage was only true until the beans got to a certain size, then their weight dropped them down again.
I remember watching a gardening program in the 80’s where the presenter was emphasising the speed at which you needed to cook sweetcorn from the moment it was picked as the sugars started to turn to starch. In those days the only way to taste good sweet corn was to grow your own. Sweetcorn breeding has come a long way since then with the development of the tender sweet and then super sweet varieties, both of which are much sweeter and also have a longer shelf life which means no more running from plot to plate!
