bush beans

I remember reading something about a variety of beans called bush beans. I have a large cold frame that I built almost two foot high at the back.

I figure I might be able to grow more tender things in the frame. How big do these bush beans grow or can anyone recommend a variety of low growing beans?

Last year I grew Minidor Yellow bush beans from Real Seeds - bear in mind it was a cold May and hardly any rain all spring/early summer, the plants barely grew more than a foot in height but the crop per plant was amazing.

I am really glad to hear this.  I am going to sow my Minidor's tomorrow.
