Eschscholzia californica Cham.
California Poppy, California Gold Poppy
Papaveraceae (Poppy Family)
USDA Symbol: ESCA2
Feathery, highly-dissected, blue-green leaves clasp the 1-2 ft. stems of this popular, perennial wildflower. Showy, 1-3 in. wide, four-petaled flowers are open only on sunny days. The flowers are solitary and long-stalked and vary in color from orange to yellow. Each of the satiny petals has a deep-orange spot at its base.
California poppy is often used in wildflower mixes. It is easy to grow, drought tolerant, and reseeds so readily that is can become weedy. In natural conditions, it blooms most heavily from March to May. This bloom period can be extended with supplemental water.
The genus is named after Dr. J.F. Eschscholtz who lived from 1793 to 1831. He performed duties as a surgeon and naturalist with Russian expeditions to the Pacific coast from 1815 to 1818.
