Texas Bluestem Pricklypoppy (Argemone albiflora ssp. texana)
This is an extremely prickly annual or biennial, usually growing 1 1/2-2 ft., but sometimes reaching 5 ft. in height. Subtended by leaf-like, spiny bracts, the white blooms are 4-6 in. across with fragile, crinkled petals and numerous yellow or red stamens. White prickly poppy’s blue-green leaves are lobed, spiny, and covered with a whitish bloom.
Seeds and other plant parts can be toxic if ingested. Sensitivity to a toxin varies with a person’s age, weight, physical condition, and individual susceptibility. Children are most vulnerable because of their curiosity and small size. Toxicity can vary in a plant according to season, the plant’s different parts, and its stage of growth; and plants can absorb toxic substances, such as herbicides, pesticides, and pollutants from the water, air, and soil.
