Invasive Ground Covers of Southern California

Hedera spp (ivies)
Hedera helix English ivySome ivy species in the Hedera genus are a problem in California. They can smother understory vegetation, kill trees, and harbor non-native rats and snails. It's difficult to distinguish problem species from less invasive ones. Do not plant ivy near natural areas, never dispose of ivy cuttings in natural areas, and maintain ivy so it never goes to fruit. Researchers hope to determine which ivies can be planted safely.

Carpobrotus edulis
Carpobrotus edulis highway iceplantThis vigorous groundcover forms impenetrable mats that compete directly with native vegetation, including several rare and threatened plants. Small mammals can carry seeds of iceplant from landscape settings to nearby natural areas. Pieces of the plant can be washed into storm drains and into natural areas where they become established.

Invasive Ornamental Grasses of Southern California
-
Arundo
Arundo donax giant reedThis grass grows along streamsides, where it can reach over 20 feet tall. It grows in dense thickets that clog waterways and is a fire hazard. When clumps of arundo are washed downstream during storms, they become trapped against bridges and create a maintenance problem where they land. Arundo creates less shade than the native trees it replaces, increasing water temperatures to a level that is dangerous for native fish.
Invasive: Do Not Plant -
Cortaderia subspecies
Cortaderia jubata jubatagrass; pink pampasgrassCortaderia selloana pampasgrass; white pampasgrassWind can carry the tiny seeds of these plants up to 20 miles. The massive size of each pampas grass plant with its accumulated litter reduces wildlife habitat, limits recreational opportunities in conservation areas, and creates a fire hazard.
Invasive: Do Not Plant -
Pennisetum setaceum (green fountain grass)
Pennisetum setaceum crimson fountain grass; purple fountain grass; tender fountain grassSpreads aggressively by seed into natural areas by wind, water, or vehicles. Fast grower; impedes the growth of locally native plant species and eventually takes over natural areas. Also raises fuel loads and fire frequency in natural areas. Is spreading rapidly in California. Existing research indicates that red varieties of fountain grass P. setaceum 'Rubrum' are not invasive.

Genista monosperma bridal veil broomGenista monspessulana French broom; soft broom; canary broom; Montepellier broomCytisus striatus Portuguese broom; hairy-fruited broomCytisus scoparius Scotch broom; English broom; common broomSpartium junceum Spanish broomBrooms have invaded over one million acres in California. The flowers produce thousands of seeds that build up in the soil over time, creating dense thickets that obliterate entire plant and animal communities. Grows quickly, creating a fire hazard in residential landscapes. "Sterile" varieties haven't been independently verified or tested and are not recommended as substitutes.
"Sweet broom" (Cytisus spachiamus or Genista racemosa) is not known to be invasive. However, because we lack information on its potential for invading wildlands, we do not recommend it as a substitute for other brooms.
