Material usesThere are no material uses listed for Eschscholzia californica.
The Californian poppy is a bitter sedative herb that acts as a diuretic, relieves pain, relaxes spasms and promotes perspiration. The whole plant is harvested when in flower and dried for use in tinctures and infusions. It is taken internally in the treatment of nervous tension, anxiety, insomnia and incontinence (especially in children). The watery sap is mildly narcotic and has been used to relieve toothache. It is similar in its effect to the opium poppy (Papaver somniferum) but is much milder in its action and does not depress the central nervous system. Another report says that it has a markedly different effect upon the central nervous system, that it is not a narcotic but tends to normalize psychological function. Its gently antispasmodic, sedative and analgesic actions make it a valuable herbal medicine for treating physical and psychological problems in children. It may also prove beneficial in attempts to overcome bedwetting, difficulty in sleeping and nervous tension and anxiety. An extract of the root is used as a wash on the breasts to suppress the flow of milk in lactating females.
Seed - sow in mid spring or late summer to early autumn in a sunny border outdoors and only just cover the seed. Autumn sown plants may require protection from frosts in cold winters. The seed usually germinates in 2 - 3 weeks.

Prefers a poor sandy soil and a sunny position but is easily grown in an ordinary garden soil. Succeeds in a hot dry position. Plants grow well in maritime climates. A very ornamental plant, it is commonly grown in the flower garden and there are many named varieties. This plant is the state flower of California. Although a perennial it is usually quite short-lived and is more often grown as an annual in this country. It can tolerate temperatures down to about -10°c, however, and often survives mild winters. If the dead flowers are removed before they set seed the plant will continue flowering for a longer period. A polymorphic species. Plants resent root disturbance and should be sown in situ. The flowers are very attractive to bees. They close during wet or overcast weather. Plants often self-sow if the soil is disturbed by some means such as hoeing.
