Dallisgrass Seedhead

John D. Byrd, Mississippi State University, Bugwood.org


Dallisgrass is a perennial, grassy weed. The leaf blades are ½ inch wide and 4 to 10 inches long, and form slowly spreading clumps. If left unmowed, flower stalks can reach up to 5 feet high, with two to 10 drooping spikelets of small, egg-shaped seeds. The seedhead includes three to five spikes branching off the center and each spike can measure 2 to 4 inches long.

It sprouts in early spring, but can grow all year round in warm climates—most prominently in low, wet ground and high-cut lawns.


Dallisgrass is mainly found in the warmer Southern states.
