I have grown these as my main bean for many years. Bronco has always been a top producer. During peak I can pick a paper grocery bag full from a 20' row every 3 days. They are straight and long and have an excellent flavor raw or cooked. Plant every 2 weeks for a whole summer of beans. Give them good air circulation or in a wet year you can get rot on the bottoms of the fruit that touch the ground. They don't need any support.
