Bluestem Prickly Poppy

Bluestem Prickly Poppy, Argemone albiflora

Also known as white prickly poppy, bluestem prickly poppy is a native of the south and southeastern portions of the United States, but has escaped cultivation and spread northward. The annual can reach heights of up to 2 m (6 ft) with a large, white bloom present from March until July. In addition to the prickly leaves and stem, the plant contains an irritating white juice that dries to a yellow latex.
