The development of the herb crops contrasts strongly with that of the other crops Whereas these the other crops have continued to be staples, and to judge by their behavior during the last century may be considered to have improved in quality and yield since that ancient time, the former have dropped to the most subordinate position of all food plants. They have lost in number of species, and have shown less improvement than perhaps any other groups of plants cultivated for economic purposes.
During the century just closed only one species, parsley may be said to have developed more than an occasional improved variety. And even during this period the list of species seems to have been somewhat curtailed—tansy, hyssop, horehound, rue and several others being considered of too pronounced and even unpleasant flavor to suit cultivated palates With the exception of these few species, the loss of which seems not to be serious, this absence of improvement is to be regretted, because with improved quality
would come increased consumption and consequent beneficial results in the appetizing flavor of the foods to which herbs are added. But greatly improved varieties of most species can hardly be expected until a just appreciation has been awakened in individual cultivators, who, probably in a majority of cases, will be lovers of plants rather than men who earn their living by market gardening.
