Botanical Name

ARGEMONE munita

Plant Common Name

Flatbud Pricklypoppy, Pricklepoppy

General Description

The enormous white crepe paper flowers are beguilingly at odds with the rest of this prickly short-lived perennial from dry regions of western North America. Borne on stout spiny stems that can vary from calf- to waist-high, the white, four- to six-petaled blooms open from bristly buds in late spring and summer. A powderpuff cluster of numerous yellow stamens ornaments the center of each flower. The blossoms are held above handsome dense clumps of deeply lobed gray-green leaves that are prickly on all surfaces. Spiny pods filled with copious seed follow the flowers. Plants exude yellow sap that has toxic properties: see http://www.wildflower.org/plants/result.php?id_plant=ARMU.

This is a fine plant for sun drenched arid gardens. It does well from the desert floor to high altitudes in rocky or sandy soil. Sow seeds directly in the garden or in individual containers to obviate transplanting and minimize root disturbance. This often short-lived plant will usually self-sow, potentially to nuisance levels in more formal areas of the garden. Few desert wildflowers are as showy in bloom.
