EXOTIC INVASIVE MUSTARD No. 3, Indian Hedge Mustard

There's a third exotic mustard that is just now forming solid stands along Caltrans (California Dept. of Transportation) roadsides in the Mojave, with the potential to get firmly established in new FHWA highway construction, like along Cal. 58 in Kern County.

About an acre along the new construction of Cal. Hwy. 58 at PM 12.00 on the north side, SISYMBRIUM ORIENTALE or the INDIAN HEDGE MUSTARD, and there's many miles already established along the roadsides of US 395, from Kramer Junction (Cal. 58 junction), north to the ghost town of Johannesburg.

This species is poised to take advantage of the Caltrans and Federal Highway Administration's funded widening of Highway 58, from Kramer Junction to the town of Mojave. After construction, there has been no replanting of the local native desert plants along the roadsides, leaving miles of roadsides and medians of Highway 58 as one huge bare area, just ready for an exotic plant to colonize.
