Roemeria argemone, commonly known as Long Pricklyhead Poppy, is an annual herb in the Papaveraceae family. It is native to the Mediterranean region, including temperate zones of North Africa, Europe, and Western Asia, with its range extending to countries such as Algeria, Egypt, Morocco, and Turkey. This species typically inhabits open fields, grassy slopes, and disturbed sites. It can reach up to 20 inches in height and is characterized by branching stems covered in stiff prickly hairs, fern-like leaves, and solitary, cup-shaped flowers that are usually red with a black base, blooming in late spring to early summer. The flowers are moderately showy and followed by elongated seed capsules.

Long Pricklyhead Poppy is not commonly cultivated but may be of interest for its unique appearance and ease of self-seeding in wildflower meadows or informal garden settings. It prefers full sun to part shade and thrives in well-drained soils. While it is drought-tolerant once established, moderate watering can encourage more robust growth. Gardeners should be cautious, as Roemeria argemone can become potentially invasive outside its native range, particularly in similar Mediterranean climates. It is important to check local regulations before planting, as it may be considered a noxious weed in some areas.CC BY-SA 4.0
