Weed Gallery: Johnsongrass--UC IPM Identification: Weed Photo Gallery Johnsongrass, a coarse and generally clumping grass, is one of the most troublesome of perennial grasses. It rapidly produces colonies, is very competitive with crop plants, and is especially a problem in California cotton fields. In California, johnsongrass is found in the Central Valley, Cascade Range foothills, Western California, and the Sierra Nevada foothills to about 2600 feet (800 m). It inhabits agricultural land, and other disturbed sites. Johnsongrass hybridizes with grain sorghum (milo). Under certain conditions, the leaves of johnsongrass (and sorghum) can produce toxic amounts of hydrocyanic acid, which can poison livestock when ingested. It is a highly variable species with some regional biotypes.
