I am a very amateur backyard gardener with much less than ideal gardening conditions. I planted these beans on a whim last year, along with several other kinds of beans, and this year they are the only beans I am planting. They have a rich, satisfying flavor, and we liked them even when they had gotten pretty large. They were always tender and never stringy. The purple stripes make them easy to spot. I should have done succession planting, but I did not. Even so, I was harvesting beans until very late in the season. Production tapered off, but I was still getting beans.
