About
Eschscholzia californica, the California poppy, golden poppy, Mexican poppy, California sunlight or cup of gold, is a species of flowering plant in the family Papaveraceae, native to the United States and Mexico. It is cultivated as an ornamental plant flowering in summer (spring in southern Australia), with showy flowers in brilliant shades of red, orange and yellow (occasionally pink and white). It is also used as food or a garnish. It had various uses in indigenous herbalism. It became the official state flower of California in 1903.
How to grow it
E. californica is drought-tolerant, self-seeding, and easy to cultivate. It is best grown as an annual, in full sun, and well-draining sandy or loam soil. Horticulturalists have produced numerous cultivars with a range of colors and blossom and stem forms. These typically do not breed true on reseeding. Seeds are often sold as mixtures. The following cultivars have gained the Royal Horticultural Society's Award of Garden Merit:-
'Apricot chiffon' (yellow flushed with pink and orange)
Uses
California poppy leaves are used as food or garnish, while the seeds are used in cooking. There are no clinical trials showing it can effectively treat psychiatric disorders in humans.
