Cichorium spinosum, commonly known as prickly chicory or spiny bittercress, is a biennial or perennial plant native to the Mediterranean region, including Cyprus, East Aegean Islands, Greece, Italy, Kriti, Libya, Sicilia, and Spain. This hardy plant thrives in full sun and prefers soil that can be light (sandy), medium, or heavy (clay), making it adaptable to various growing conditions. It is well-suited for hardiness zones 6-9. One distinctive feature of Cichorium spinosum is its spiny leaves, which are edible and can be used in salads or cooked as a vegetable. The leaves are also used to make tea, adding a bitter yet refreshing flavor to beverages. While its ornamental value is limited due to the prickles, the plant remains a notable presence in gardens and natural settings. Traditionally, Cichorium species have been used in European herbal medicine for digestive issues, such as indigestion and bloating. A decoction of the leaves may help support healthy digestion. Additionally, these plants have been used to support the immune system, with a tea made from the leaves potentially helping to maintain overall health. However, it is important to use caution when handling the plant due to its spines, and it is recommended to wear gloves when harvesting the leaves.

The polysaccharides and flavonoids found in Cichorium species are thought to enhance immune function, although specific mechanisms for Cichorium spinosum have not been fully elucidated.
Start with a simple, light-loving plant that thrives in well-draining soil and full sun.
Seeds or seedlings, potting mix, containers or garden space.
Plant in spring after the last frost when temperatures are mild.
Use a well-draining soil with a pH between 6.0 and 7.5, ensuring containers have drainage holes.

Water regularly to keep soil moist but not waterlogged, and protect from strong winds.
Provide full sun exposure and regular watering. Fertilize lightly every 4-6 weeks with a balanced fertilizer.
