California Poppy
Nomenclature
Eschscholzia californica
Family: Papaveraceae
Descriptive Characteristics
Annual flower 1-2 feet in height, long stalks with grayish green foliage. Leaves are long and divided in round, lobed segments. Flowers are long stems with four wide fan shaped petals that are silky. Colors range from yellow to orange. Flower from February to September. Fruit is slender and podlike and splits into 2 to release small black seeds.
Harvest when the flower is flowering.
Propagate seeds in a sunny border outdoors. They do not transfer well so plant them where you want them. Thin the keiki so that they stand 6 to 8 in apart. Pull entire plant from ground to harvest. Dry in paper bag.
Active Constituents
Eschscholtzine, californidine, sanguinarine, chelerythrine
Flavone glycosides and Alkaloids such as protopine, cryptopine, and chelidonine similar to Opium Poppy.
