“ The kidney bean is not very well suited to very high northern latitudes, since it is particularly sensitive to the cold, even if the temperature is not low enough to produce frost. The kidney bean is cultivated over large areas and is also a garden crop. There are early and late varieties, so that the season for the kidney bean is a long one. The pods of this bean are distinguished by being long and slender, and it is particularly valuable for edible purposes while green and is also prized for canning. This is true, especially, of that variety which has a tender pod. ”
