Within the UAE, the species is moderately widespread (Jongbloed et al. 2003) along the northern Arabian Gulf north to Ras al Khaimah (Western 1983) and east coasts, Al Ain (Mousa and Fawzi 2009), and on Das Island. The species is also found in Wadi Wurayah National Park (WWNP), where it is a ruderal species seen at donkey resting sites and formerly inhabited terraces, probably facilitated by man and domestic animals (Feulner 2016), and also in the Ru'us al-Jibal, again associated with disturbed ground, trails, and cultivation (Feulner 2011). This species has been considered introduced to the UAE (Pagad et al. 2017), but the majority of the of the UAE native plant working group (June 2019) considered the species to be native and so it is assessed here as such. This species is considered native to large areas of Europe, North and East Africa, the Arabian Peninsula and South Asia by Plants of the World Online (Board of Trustees, RBG Kew 2019). However, CABI (2018) consider the species to probably be native to the Mediterranean region, although it has been widely introduced globally.
