Dendromecon rigida is a small perennial
shrub, rarely exceeding tall. The
leaves are alternate, narrow lanceolate, 3–10 cm long, more than three times as long as broad. The margin of the leaves is finely toothed. The plant is evergreen and the leaves are somewhat leathery to the touch. The
inflorescences are solitary and terminal. The
flowers are 2–7 cm diameter, with four satiny yellow petals. Plants bloom in late winter to mid-spring. The receptacle is funnel-shaped and surrounds the
ovary base. Two
sepals are shed when the flower blooms, and the
petals are shed as well after pollination. There are many free
stamens. Flowers bloom April to June. . ==Cultivation==
