A Characteristic Shirley Poppy Specimen
This picture gives a very good idea of the characteristic texture of petals in the Burbank improved Shirley poppy. Mr. Burbank says that the plant did not at first respond to his efforts, but that after a few seasons it progressed very rapidly. When the experiment was at its height he had several men in the fields every morning during the time of blooming, on the lookout for the slightest variation in the desired direction.
