EschscholziaSee text Eschscholzia is a genus of 12 flowering plants in the Papaveraceae (poppy) family. The genus was named after the Baltic German botanist Johann Friedrich von Eschscholtz (1793-1831). Many of the plants in this genus are annuals or perennials with deeply cut glabrous or glaucous leaves. These are mostly basal, but a few grow on the stem. They feature showy four-petaled yellow or orange terminal flowers, growing solitary or in many-flowered cymes. They are funnel-shaped. The two fused sepals fall off as the flower bud opens. The petals are wedge-shaped. There are 12 to numerous stamens. They develop a cylindrical, dehiscent fruit, giving off many tiny seeds. Thery are widely cultivated. These flowers have the habit of closing in cloudy weather. The taproot gives off a colorless or orange milky juice. These plants are toxic. The best-known is the California Poppy (Eschscholzia californica), the state flower of California; others include E. caespitosa and E. mexicana. Species They prosper in warm, dry climates, but withstand some frost. They grow in poor soils with good water drainage.
