Russian Thistle, also known as Tumblingweed, is a prickly annual plant that is considered a nuisance weed in many regions. It is native to the dry regions of Eastern Europe, Western Asia, and Southern Russia. Russian Thistle has several synonyms, including Salsola tragus, prickly saltwort, and tumbleweed. The plant is known for its ability to break off from the roots and tumble across the landscape, scattering seeds as it goes. This feature has earned it the name Tumblingweed. The plant is also called prickly saltwort due to its prickly leaves and stems. Regardless of its name, Russian Thistle is a hardy, adaptable plant that continues to spread globally.
