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 with moist soil that can be light (sandy), medium, or heavy (clay) and is well-suited for zones 6-9. One distinctive feature of Cichorium spinosum is its spiny leaves, which are edible and often used in salads. Its ornamental value is limited due to the prickles but it remains a notable presence in gardens and natural settings.
