Eschscholzia californica (California poppy, golden poppy, California sunlight, cup of gold) is a species of flowering plant in the Papaveraceae family, native to the United States and Mexico. It is an ornamental plant flowering in summer, with showy cup-shaped flowers in brilliant shades of red, orange and yellow (occasionally pink). It is also used as food or a garnish. It became the official state flower of California in 1903.
It is a perennial or annual plant growing to 5–60 in (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 (0.79 to 2.36 in) long and broad; flower color ranges through yellow, orange and red (with some pinks). Flowering occurs from February to September in the northern hemisphere (spring, summer, fall). 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 to release numerous small black or dark brown seeds. It survives mild winters in its native range, dying completely in colder climates. (Wikipedia) Photo credit: By Kaldari CC0.
