Bush of Santa Rosa Shirleys
The modifications both in the petals-which have been given a very characteristic delicacy of texture, combined with firmness-and in the stem of the plant and its manner of growth effected by Mr. Burbank are so striking that it has been suggested that his type of Shirley poppy should be given a new name. He prefers, however, to retain the name Shirley, in recognition of the work of the experimenter who first produced the variety.
