The California poppy, Eschscholzia californica [es-SHOLT-zee-uh] [kal-ih-FOR-nik-uh] is a perennial flowering plant belonging to the Papaveraceae family.
It was the first named species of the Eschscholzia genus named by Adelbert von Chamisso for botanist Johann Friedrich von Eschscholtz after an expedition to the Pacific and California aboard a Russian ship circa 1810.
It’s native to the United States and Mexico.
Since 1903 the wildflower became the official state flower of California. April 6 is California Poppy Day.
This flower has extended into Oregon, Washington, Nevada, Arizona, New Mexico, Sonora, and northwest Baja California.
This southern California native plant was valued by Native Americans who used the golden state flower as a food source and for the oil extracted from the plant.
