Introduced from Europe, and now common throughout the United States.

Latin Name: Dactyloctenium Aegyptium

Introduced from the Old World Tropics of Asia or Africa, and now found throughout much of the U.S., particularly in the southern states, and south throughout Latin America, in Europe, Australia, and Hawaii.


Latin Name: Paspalum Dilatatum

Giant Reed

Latin Name: Arundo Donax

Native to warmer areas of Europe, and introduced to California as an ornamental and wind-break planting, as well as for use as a roofing material, mats or screens. It easily escapes cultivation and has become a major problem in natural settings due to its aggressive and dominating growth. In particular it is noxious in areas along river shores, irrigation or ditchbanks, and drainage canals. It grows in tall, solid thickets that may overwhelm large areas.


Latin Name: Eleusine Indica

Introduced from Europe, but now found throughout most of the United States.

Italian Ryegrass

Latin Name: Lolium Multiflorum

A native of Europe, and now widespread throughout the United States.


Latin Name: Sorghum Halepense

Native to the Mediterranean region, but deliberately introduced to the United States as a grass desirable for forage. Now widespread throughout the warm regions of the U.S. where it is a severe pest weed problem.

Jungle Rice

Latin Name: Echinochloa Colona

Native to Europe, and now widespread throughout the west and southwest United States. Found commonly in both cultivated fields and in waste areas.


Latin Name: Pennisetum Clandestinum

Native to tropical Africa, but introduced deliberately to California as a cover along slopes and ditch banks for erosion control. As a very fast growing grass it also has been used for a turfgrass, but it is capable of escaping and invading other grasses where it is objectionable.

Red Sprangletop

Latin Name: Leptochloa Filiformis

Native to tropical Latin America.

Reed Canarygrass

Latin Name: Phalaris Arundinacea

Native to Eurasia, and now found throughout the northern United States and Canada.


Latin Name: Bromus Catharticus

Ripgut Brome

Latin Name: Bromus Diandrus

Native to Europe, and now widespread along the Pacific Coast states. It is a very common weed species in rangeland, roadsides, waste areas, or ditchbanks, where it may compete with native plants.
