Zilla spinosa’s robust root system enables it to thrive in harsh desert conditions

Home to over 550 wild and grazing plant species, the King Salman bin Abdulaziz Royal Reserve stands as a vital ecological treasure in Saudi Arabia. Spanning key regions such as Northern Borders, Al Jouf, Tabuk, and Hail, the reserve plays a critical role in nutrient cycling and sustaining biodiversity. Among its many resilient plants is Zilla spinosa — a hardy, low-growing perennial known for its drought tolerance, waxy purplish-green leaves, and vibrant purple flowers that attract bees and support pollination.
