Eschscholzia californica, the California poppy, golden 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.

Description

 

 

The same patch of California poppies, with petalopen on a sunny day (above) and closed on a chilly evening (below).

California poppy is a perennial or annual plant growing to 5–12 in (13–30 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 (0.79 to 2.36 in) long and broad; flower color ranges through yellow, orange and red. Flowering occurs from February to September in the northern hemisphere. 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 (1.2 to 3.5 in) long, which splits in two, sometimes explosively with an audible snap, to release numerous small 1.5–1.8 mm (0.059–0.071 in) wide black or dark brown seeds. The plant will reseed under ideal conditions, or when winters are cold. Anecdotally, it can be an aggressive reseeder in the home garden context, eventually becoming a groundcover. It survives mild winters in its native range, dying completely in colder climates.
