Eschscholzia californica is native to the cool and moderate expanses of the western United States and Mexico and has been the official state flower of California since 1903. Colusa and San Luis Obispo counties are homes to stunning and natural rolling meadows of the iconic golden orange California poppy. The genus Eschscholzia honors pioneering Baltic German naturalist and entomologist Johann Friedrich von Eschscholtz who explored California and the greater Pacific northwest in the early 19th Century.
