Guineagrass

Nonnative to FloridaFISC Category 2 Invasive

Species Overview

Origin: Africa

Here is another large nonnative grass growing in Florida. Guineagrass 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).

Guineagrass may be found from Florida and Georgia to California and Hawaii (Kartesz, 1999).
