DESKTOP 2093 - CALIFORNIAN POPPY

Eschscholzia californica (Californian poppy, golden poppy, California sunlight, cup of gold) is a species of flowering plant in the family Papaveraceae, native to the United States and Mexico, and the official state flower of California. It is a perennial or annual growing to 13–152 cm tall, with alternately branching glaucous blue-green foliage. The leaves are alternately divided into round, lobed segments.

The flowers are solitary on long stems, silky-textured, with four petals, each petal 2 to 6 cm long and broad; flower colour ranges from yellow to orange, with flowering from February to September. The petals close at night or in cold, windy weather and open again the following morning, although they may remain closed in cloudy weather. The fruit is a slender, dehiscent capsule 3 to 9 cm long, which splits in two to release the numerous small black or dark brown seeds. It survives mild winters in its native range, dying completely in colder climates.

E. californica is drought-tolerant, self-seeding, and easy to grow in gardens. It is best grown as an annual, in full sun and sandy, well-drained, poor soil. Horticulturalists have produced numerous cultivars with a range of colours and blossom and stem forms. These typically do not breed true on reseeding. Seeds are often sold as mixtures. Many cultivars have gained the Royal Horticultural Society's Award of Garden Merit. Because of its beauty and ease of growing, the California poppy was introduced into several regions with similar Mediterranean climates.

It is commercially sold and widely naturalised in Australia, and was introduced to South Africa, Chile, and Argentina. It is recognised as a potentially invasive species within the United States, although no indications of ill effects have been reported for this plant where it has been introduced outside of California. The golden poppy has been displaced in large areas of its original habitat, such as Southern California, by more invasive exotic species, such as mustard or annual grasses.
