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. Full article

Smooth golden fleece (Urospermum dalechampii (L.) F.W. Schmidt) and prickly golden fleece (Urospermum picroides (L.) Scop. ex F.W. Schmid) are two wild edible plants used in traditional cuisine and folk medicine. In this research, the domestication of both species was tested for the first time using a floating system and two plant densities (412 and 824 plants m⁻²) to evaluate yield and quality. Some quality traits were also compared in cultivated plants and wild ones gathered in grasslands. The results show that both species are suitable for cultivation, although prickly golden fleece showed highest total phenols (132 mg 100 g⁻¹ fresh weight—f.w.) and total antioxidant activity (0.19 mg 100 g⁻¹ f.w.). At low sowing density, smooth golden fleece showed a nitrate content of about 7200 mg kg⁻¹ f.w., 38% higher than plants of the same species grown at high density and plants of prickly golden fleece. These results suggest that high density can be used to optimize yield in two harvests. By permitting modulation of nutrients and a product without soil residues, the floating system used in this study proved suitable for growing U. dalechhampii and U. picroides as new vegetables for the ready-to-eat production chain.
