Paspalum floridanum is a species of grass known by the common name Florida paspalum. It is native to the eastern United States.[1]

This rhizomatous perennial grass has stems which can exceed two meters in height. The leaf blades are up to 52 centimeters long and may be hairless to hairy, with a dense coating of hairs behind the ligules. The inflorescence is a panicle with up to 6 branches. The paired spikelets are generally oval in shape and measure a few millimeters long.[1]

This grass grows in disturbed, wet habitat types such as ditches. It grows in woods and marshy areas.[2]

The seeds provide food for birds.[3]
