A Santa Rosa Shirley
A flower with such tendency to vary as the Shirley poppy has manifested naturally appealed to Mr. Burbank. He has experimented very widely with this variety of poppy, and has modified it very markedly, particularly with reference to the texture of its petals. By rigid selection among many thousands of specimens, conducted year after year, Mr. Burbank has so modified and improved the Shirley that seedsmen usually sell his varieties as the improved Shirley poppy, or the Santa Rosa strain of the Shirley poppy.
