A Double Red Shirley Poppy
The general appearance of this flower would scarcely cause one to associate it with the flowers shown in the preceding pictures. But it is only a Shirley poppy modified in yet another direction. Like the other modifications in the form and color of the Shirley, this condition of double petals has been developed by selective breeding along the lines elsewhere clearly explained.
