Cladus: Eukaryota Name Eschscholzia Cham., Horae Phys. Berol. (C G.D.Nees) 73. 1820. Type species: E. californica Cham. Vernacular name References * ITIS: Eschscholzia Eschscholzia (pronounced /ɛˈʃɒltziə/) is a genus of 12 annual or perennial plants in the Papaveraceae (poppy) family. The genus was named after the Baltic German botanist Johann Friedrich von Eschscholtz (1793-1831).
Leaves are deeply cut, glabrous or glaucous, mostly basal, though a few grow on the stem. Flowers have four yellow or orange petals, and grow at the end of the stem, either alone or in many-flowered cymes. The petals are wedge-shaped, forming a funnel. The two fused sepals fall off as the flower bud opens. There are 12 to numerous stamens. The flowers close in cloudy weather. Seeds are tiny and black, held in long pointed pods that split open when ripe. The taproot gives off a colorless or orange milky juice, which is mildly toxic. Cultivation The best-known is the California Poppy (Eschscholzia californica), the state flower of California. Eschscholzia caespitosa is very similar to E. californica, but smaller and without a collar below the petals. Another common in cultivation is Eschscholzia lobbii, which is often sold as Eschscholzia caespitosa. E. lobbii has yellow flowers and very narrow leaves. They prosper in warm, dry climates, but withstand some frost. They grow in poor soils with good water drainage. Species * Eschscholzia caespitosa—Tufted Poppy, Foothill Poppy, Collarless California Poppy
