See text Eschscholzia /ɛˈʃɒltsiə/[1] is a genus of 12 annual or perennial plants in the Papaveraceae (poppy) family.

The genus was named after the Baltic German/Imperial Russian botanist Johann Friedrich von Eschscholtz (1793–1831).

Leaves are deeply cut, glabrous and 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.

Eschscholzia caespitosa is very similar to E. californica, but smaller and without a collar below the petals.
