Had anyone asked me, I would have said that tumbleweeds were native to the US.
"Tumbleweed," "Russian thistle" and "wind witch" are common names for this symbol of the American west. Russian thistle alludes to its Eurasian origin. Although tumbleweed is native to the arid steppes of the Ural Mountains in Russia, it is now ubiquitous throughout the western states, growing in disturbed soils such as agricultural fields, irrigation canals and roadside shoulders and ditches. Plants thrive in salty and alkaline soils but will generally be outcompeted by natives in undisturbed habitats. Elevation range is from below sea level in Death Valley to over 8500 feet.
Tumbleweeds were first reported in the United States around 1877 in Bon Homme County, South Dakota, apparently transported in flax seed imported by Ukrainian farmers. Within two decades it had tumbled into a dozen states, and by 1900, it had reached the Pacific Coast.
Salsola is derived from the Latin sallere, "to salt," in reference to the plant’s salt tolerance. |
