Eschscholzia californica – California poppy

State Flower of California – The California poppy (Eschscholzia Californica) was designated the state flower of California in 1903.

Cal poppy also known as 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, with showy cup-shaped flowers in brilliant shades of red, orange and yellow (occasionally pink). It is also used as food or a garnish.
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.
