    Here is another large non-native grass growing in Florida. Guinea grass is native to Africa and blooms year round. It is common in fields, groves, roadsides and other disturbed sites from the peninsula west to the central panhandle of Florida and Escambia county (Wunderlin, 2003). It looks very similar to another invasive plant, Johnson grass (Sorghum halepense).

    Guinea grass may be found from Florida and Georgia to California and Hawaii (Kartesz, 1999). (Kartesz refers to this plant as Urochloa maxima.)

    See the UF/IFAS Assessment, which lists plants according to their invasive status in Florida.
