Synonyms: formerly considered part of Russian thistle species (Salsola iberica or Salsola tragus)
Common names: barbwire Russian thistle
Salsola paulsenii (barbwire Russian thistle) is a bushy annual (family Chenopodiaceae) found throughout the Mojave Desert of California. It prefers loose, sandy soils in desert scrub and disturbed areas, such as roadsides and cultivated fields. Barbwire Russian thistle is easily confused with Russian thistle (Salsola tragus), and the two species can hybridize, making a plant that looks like a mix between the two species. Both species reproduce using seeds which can only survive for up to two years in the soil. Cultivation can effectively control barbwire Russian thistle seedlings, but must be repeated until all seeds in the seedbank loose viability.Cal-IPC Rating: Limited
