Guinea grassPanicum maximum(sometimes listed as Urochloa maxima)Identifying CharacteristicsOriginally from Africa; introduced agriculturally asanimal fodder. Leaves are long and narrow, flat and brightgreen, fine and soft. Hairy leaves, 1 /2 to 1 1 /4 inches wide,can grow 5 to 39 inches long. Margins are glabrous(smooth or hairless). Tiny flowers are on inflorescentspikelets and are green or tinged with purple. Plants cangrow 3 to 9 feet tall.HabitatGrows naturally in open grasslands. Usually formscolonies under or near trees and shrubs on abandonedcultivated land, fields and wastelands.Growth HabitsConsidered an invasive weed because the grass suppressesor displaces local plants. This tufted perennial grassusually grows in large bunches from short stout rhizomesand grows on a wide variety of soils, in both sun andshade. Can survive long, dry periods, as well as fire. Theunderground rhizomes are not harmed by fire and maytherefore dominate after a fire. Responds quickly towatering and fertilizer. Seeds are dispersed by wind, birdsand flowing water.Control Methods: FoliarMow, then wait until grass grows to 6 inches to applyglyphosate or imazapyr. Reapplications will be necessary.ReplacementsMuhly grass (Muhlenbergia capillaris)Love grasses(Eragrostis elliottii or E. spectabilis)Eastern gamma/Fakahatchee grass(Tripsacum dactyloides)25
