The leaves resemble those of the closely related Eschscholzia, being finely divided into many gray-green linear lobes. The flowers are solitary yellow cups formed from four overlapping petals, 5–7 cm across, vaguely resembling the unrelated tulip; the two sepals underneath typically fall away as the flower opens.
