Glaucium grandiflorum grows NaNcm (-2,147,483,648inches) and can have one or more main stems. These stems are branched, and are covered with rather dense hairs. The petals are NaNcm (-2,147,483,648inches) long. There are numerous stamens with anthers NaNmm in length. Their filaments are monotronic in the upper half and broadened in the lower half. The pedicals, when fruiting, can be up to 9cm (04inches) long, and are erect or contorted and hairy. The stigma are NaNmm broad.[2]
Numerous alkaloids have been isolated from the plant, including norchelidonine, dihydrochelerythrine, 8-acetonyldihydrochelerythrine, protopine, allocryptopine, corypalmine, and tetrahydropalmatine.[3]
