Opium poppy

Papaver somniferum

Papaveraceae

The garden poppy that also yields opium — a beautiful annual whose latex is the source of morphine, codeine, and a century of addiction medicine.

The plant is widely sold as an ornamental and as breadseed poppy. Extracting opium, morphine, or heroin from any part of it is a serious crime. Concentrated poppy-seed tea has caused deaths. Seeds as food are legal; 'unwashed' seed sold for tea is a gray, dangerous market.

Parts used: Ripe dry seed (food only) · Latex — pharmaceutical / illegal
Traditional notes: Historical anesthetic and antidiarrheal (obsolete as self-care) · Bread seed and poppy-seed oil (food)
Habitat only: Old-world annual of disturbed ground. Breadseed strains are common in ornamental catalogs. The plant itself is not rare.

Culinary seed poppies are a garden annual in many places. Latex is not a crop.
Do not score pods. That is the line between a flower and a controlled substance.
If your jurisdiction restricts even ornamental pods, skip the bed.

Lore

The same annual as the bakery seed. Scoring a green capsule is an old agricultural act and a modern crime. Morphine was isolated in 1804 and named for Morpheus; the plant is older than the word.
