California State Flower: Poppy

The California poppy (Eschscholzia Californica) was designated the state flower of California in 1903. Also known as the flame flower, la amapola, and copa de oro (cup of gold), the California poppy grows wild throughout the state. Native Americans in California valued the poppy as a food source and for the oil extracted from the plant. Every year, April 6 is California Poppy Day and May 13th – 18th is Poppy Week.

Seeds of this plant were introduced into English gardens in the nineteenth century. Seed catalogs now offer many different colors. California poppies have been planted in most of the United States and have become established along roadsides, in empty lots, and other disturbed places. In California, it is hard to tell anymore which poppies are native wildflowers and which are garden escapes.

California poppies are easy to grow. Sow the seeds shallowly (1/16-inch deep) in fall or early spring in mild, wet winter climates, including most of California west of the Sierra-Nevada. Seeds will germinate after the first fall rains or when the soil warms in the spring. In hot summer areas, the poppies will bloom in spring and early summer, and then the tops will die back and the plants become dormant during the heat of the summer. The poppy survives in the form of a fleshy taproot. In cooler coastal climates, California poppies may bloom most of the summer. Sandy, well-drained soil in full sun is best. No supplemental watering is required unless the growing season is exceptionally dry.

In mild-winter climates, these poppies will survive several years, resprouting each fall. They will reseed themselves if they are happy. Where winters are cold, the poppy behaves as an annual, renewing itself from seed each year. The flowers of California poppy close each night, and on cloudy days. Enjoy them where they grow. If you pick California poppies for a wildflower bouquet, you will be disappointed when the petals almost immediately fall off.
