Wildland Weeds: Paragrass, Urochloa mutica (SSAGR370/AG375)

Figure 1.  Panicle-like inflorescence of Urochola mutica composed of false spikes.Paragrass (also referred to as Californiagrass) is thought to have been introduced into Florida sometime in the late 1870s as a forage plant. The semiaquatic grass is a native of tropical Africa, and today it is established in both hemispheres in tropical and subtropical regions as a highly palatable fodder. The grass is established in regions of poorly drained soils and along freshwater shorelines in Alabama, Florida, Hawaii, Maryland, Oregon, South Carolina, and Texas. It is an extremely aggressive competitor that can displace many shoreline emergent plants and plants in cultivated or disturbed sites associated with moist soil. Paragrass becomes readily established in wet soils along shorelines where it can form large monocultures. This 4-page fact sheet was written by L. T. Markle, B. A. Sellers, and W. A.

SS-AGR-312/AG318 Natural Area Weeds: Invasive Solanum spp. in Florida

SS-AGR-312, a 7-page illustrated fact sheet by L. T. Markle, W. A. Overholt and K. A. Langeland, provides a guide to differentiate the invasive Solanum species, information about the ecology and management of each species, and information on Solanum capsicoides All., which can easily be confused with some of the invasive Solanum species. Includes references. Published by the UF Department of Agronomy, December 2008.
