Other: The genus name, “Tamarix”, is named for the Tamaris River in Spain and the species name, “chinensis”, means “of China” which refers to its Eurasian distribution.
This plant from Eurasia was planted intentionally to control erosion. It reached Utah sometime following the turn of the century. It was well established by the 1920's along the Colorado River and its tributaries. It spreads so rapidly and so extensively that there is little hope of eradicating it.
