Description:

Glaucium flavum, commonly known as Yellow horned-poppy, is a perennial plant with distinct characteristics. It features thick, leathery, bluish-grey leaves that are deeply segmented and wavy. Growing on branched, grey stems, it can reach heights of 30-90 cm. The plant blooms in summer, specifically between June and October, producing bright yellow or orange flowers that are approximately 7.5 cm across. Following the flowering stage, it forms a unique horn-shaped capsule, measuring 15-30 cm in length, which eventually splits open to reveal the seeds.

Distribution and Habitat

Glaucium flavum is native to Europe, Northern Africa, Macaronesia, and temperate zones in Western Asia. It is predominantly found in coastal habitats, including shingle banks, beaches, cliff tops, and sand dunes. While it thrives in its natural environment, the plant is also cultivated in gardens as a short-lived perennial, although it is more commonly grown as a biennial.

Toxicity

It is important to note that all parts of Glaucium flavum, including the seeds, are toxic. Ingesting the plant can result in a wide range of symptoms and even respiratory failure, which can be fatal.

Medicinal Uses

Glaucine, the main alkaloid component found in Glaucium flavum, possesses bronchodilator and anti-inflammatory properties. As a result, it is used medicinally as an antitussive, or cough suppressant, in certain countries. However, it is worth mentioning that the use of Glaucine may lead to side effects such as sedation, fatigue, and hallucinogenic effects characterized by colorful visual images.
