Rtanj is known for its endemic plants that grow only on this mountain and are protected by law, and the most famous of them is certainly Rtanj tea (Saturea montana). According to oral history, it was grown centuries ago by Turks in their harems, after the liberation from their rule in the 19th century, the herb was brought to Rtanj and planted on the altitude of 1,000 meters, as it only grows there.

Early august is the harvesting time for this plan, and on that occasion the local tourist association organizes a picnic and an outdoor lunch.
