Texans I know call it "Cedar Fever". I experienced it in Austin. In New Mexico windblown indigenous Juniper pollen, which is yellow, coats everything in the spring. Also the non indigenous female Cottonwood trees there which grow mostly along riverbanks produce white cottony blizzards about this time of year. Siberian Elm trees planted all over the state by then Governor Clyde Tingley in the 1930's in the Spring produce sail like seeds which seem to enter every possible crevice and produce fast growing saplings in seemingly no time at all. (I once heard he thought he was getting Chinese Elm trees. He was not an educated man.) I guess every region contains nuisance vegetation of some sort.
Didn't Tumbleweeds (Russian Thistle) get into the USA in a shipment of wheat from Russia or by Russian immigrants back in 1873?
