  • Shrub or small tree, 5 to 20 feet tall.
  • Pale green leaves are small and scale-like, on thin stems with many branches.
  • Flowers pink to white in color, appearing from spring to late summer.

Identification key in: Hickman, J. ed. 1993. The Jepson Manual: Higher Plants of California. University of California Press.

Habitat and local distribution

  • Well-adapted to alkaline soils, wind, and a wide range of temperatures; typically found along waterways.


  • Excludes other plants from growing underneath, due to salt deposited from leaves.
  • Aggressive root system depletes ground water needed by native species.

Prevention and Control


  • Plant natives or spread native seed in disturbed areas.
  • Search threatened areas regularly (at least annually) to look for newly arrived plants.

General control notes

  • Difficult to eradicate since species spreads rapidly and usually resprouts after treatment. Follow-up monitoring to treat resprouts essential (Lovich 2000).

Manual or mechanical control

(Lovich 2000)

  • Root plowing and cutting—useful for initial removal of heavy infestations; follow-up application of herbicides suggested to treat resprouting.
  • Estimated costs: vary depending on if volunteers conduct removal and on the plant density; equipment costs range may from $100 to over $1,000 (Gibbons et al. 1999). There may be additional fees for disposal of plant material.
  • Pulling by hand—uprooting of seedlings and small plants.
  • Prescribed burning—useful for reducing biomass prior to herbicide application.
  • Flooding—effective when thickets can be flooded for one to two years.

Biological control

  • Biological control agents—USDA currently testing several insect species from other countries for release in United States (DeLoach 1997).
  • Grazing—cattle grazing can reduce amounts of sprout regrowth (Gary 1960).

Chemical control

(Lovich 2000)

  • Apply triclopyr (as Pathfinder II®) to bark of smaller stems (< 4-inch diameter); wet bark at base of stem prior to herbicide application.
  • Treatment of resprouts by glyphosate (Rodeo® or RoundupPro®) or imazapyr (Arsenal®) during growing season; only Rodeo® is registered for aquatic habitats.
  • Estimated costs: costs for materials and application by a contractor are approximately $250 per acre for glyphosate, depending on size of treatment area, scale of treatment, and herbicide dosage. It is recommended to contract a licensed professional for herbicide applications (Gibbons et al. 1999).

Integrated control

  • Cut larger shrubs and apply triclopyr (as Garlon 4® or Garlon 3A®); use of Garlon 3A® most effective when applied during growing season (Lovich 2000).
