Discussion

Halimodendron halodendron is cultivated as an ornamental in British Columbia, California, Manitoba, Massachusetts, Michigan, New York, North Dakota, Oklahoma, Ontario, Pennsylvania, Saskatchewan, Utah, and Wyoming; it has been reported from Montana. It is sometimes used for erosion control. In some climates, it survives better if grafted onto root stocks of Siberian pea tree, Caragana arborescens.

California has listed Halimodendron halodendron a noxious weed; known naturalized populations there have been eradicated (J. M. DiTomaso and E. A. Healy 2007). The species does not appear to escape cultivation readily, and reports of it being naturalized in other states (D. Isely 1998) are unconfirmed.
