Tree poppy, Bush poppy
Papaveraceae (Poppy Family)
USDA Symbol: DERI
Tree-poppy is a stiff, rounded, evergreen shrub, normally 6 ft. high but sometimes taller. The main stems have grayish or whitish, shredding bark and bear narrow, gray-green, leathery leaves. Brilliant yellow, cup-shaped flowers at ends of short branches or on long stalks in leaf axils. Four-petaled, yellow flowers with numerous stamens occur singly at the ends of short branchlets.
Tree Poppy may be very common several years after a fire in chaparral. There is only one other species in the genus, Island Tree Poppy (D. harfordii), found on islands off the coast of southern California.
