Summary
Glaucium flavum, commonly known as Yellow Hornpoppy, is an evergreen biennial herb native to coastal habitats, including sandy beaches, shingle beaches, and sea cliffs in the Mediterranean, North Africa, and Western Asia. This plant typically grows to a height of 30-60 cm (12-24 inches) and spreads 30-60 cm (12-24 inches) wide. The foliage consists of thick, leathery, deeply segmented, wavy, bluish-grey leaves coated in a water-retaining wax, which helps the plant conserve moisture in its arid native habitat.
The Yellow Hornpoppy is known for its showy, bright yellow or orange flowers, each 7.5 cm (3 in) across, which bloom in summer between June and October. Following the flowering period, it produces a very long, upright, thin, distinctive horn-shaped capsule, which is 15–30 cm (6–12 in) long and splits open to reveal seeds. This plant is valued for its drought tolerance and striking flowers, making it suitable for rock gardens, coastal gardens, and xeriscaping. It thrives in full sun and well-drained soils, tolerating low to medium water conditions. While it is not commonly afflicted by diseases, it can become invasive outside its native range, so gardeners should check local regulations before planting.CC BY-SA 4.0
