Urospermum dalechampii (Asteraceae): A Neglected Mediterranean Wild Edible Plant with Nutritional, Phytochemical and Agronomic Potential

Wild edible plants represent an underexploited resource for enhancing agrobiodiversity and promoting more sustainable food systems. Urospermum dalechampii (Asteraceae) is a traditional Mediterranean wild edible species widely used in local cuisines, yet it remains marginal in modern horticulture. This review provides an overview of the current knowledge on the nutritional composition, phytochemical profile, biological activities, and agronomic potential of U. dalechampii. Available evidence indicates that its edible tissues are characterized by a favorable nutritional profile, including appreciable levels of dietary fiber, minerals, and beneficial fatty acids. Moreover, the species is a rich source of bioactive compounds—particularly phenolic acids, flavonoids, and terpenoids—which have been associated with antioxidant, anti-inflammatory, and antimicrobial activities. Recent studies have demonstrated the feasibility of domesticating U. dalechampii through both soil-based and soilless cultivation systems, including baby-leaf and microgreen production, thereby enabling controlled yields and reducing harvesting pressure on wild populations. Nevertheless, research on this species remains fragmented, and several knowledge gaps persist, notably the absence of standardized agronomic protocols, limited information on post-harvest management and safety, and potential market constraints related to bitterness and variability in product quality. Overall, U. dalechampii emerges as a promising candidate for sustainable horticulture and the development of functional foods.
