Primarily a threat at high elevations?  no

Risk assessment results:  High risk; score: 11 (Hawaii-Pacific Weed Risk Assessment for Papaver rhoeas)

Common name(s): [more details]

English: Flanders poppy, Shirley poppy, common poppy, corn poppy, field poppy, poppy, red poppy

Habit:  herb

Description:  "P[apaver] rhoeas (field poppy) has a smooth, rounded fruiting capsule. It is a hairy annual with tall, slender stems and brilliant scarlet nodding flowers." (Western Weeds, p. 208)

"An annual or biennial plant, it grows to a height of 0.4 m with a spread of 0.4 m. ¶The stem is erect, hairy and unbranching; the leaves are basal and pinnate or bipinnate, with coarsely serrate margins; the flowers are rich scarlet, with a black blotch at the base, 4 petalled and 10 cm across." (Encyclopaedia Botanica, p. 760)

Habitat/ecology:  "A native of Asia Minor, it is adaptable to most soils, but prefers an open, sunny position. It is frost resistant but drought tender." (Encyclopaedia Botanica, p. 760)

Propagation:  In cultivation (apparently): "Propagation is by seed or by root cuttings." (Encyclopaedia Botanica, p. 760)

Native range:  The native range of Papaver rhoeas L. (Papaveraceae) includes the Madeira Islands; the Canary Islands; northern Africa (Algeria, Egypt, Libya, Morocco, Tunisia); parts of temperate Asia (Armenia, Azerbaijan, Georgia, Russian Federation, Russian Federation-Ciscaucasia, Afghanistan, Cyprus, Egypt, Iran, Iraq, Israel, Jordan, Lebanon, Syria, Turkey), Pakistan, and much of Europe. (GRIN)

Impacts and invaded habitats:  Papaver rhoeas has become established ("naturalized") in these areas where it is non-native: Azores, Australia, New Zealand, Mexico, the United States, Hispaniola, and Chile. (GRIN)
