Tridens flavus



Stems are erect, but droop when mature. The sheaths are flattened and overlapping at the base, giving a mirror image on left and right. The panicle is open, spreading and pyramid shaped. The branchlets of the panicle give off a sticky juice that causes dirt to cling to it. Spikelets have five to seven flowers and are green to pale purple when ripe. At a glance, purpletop resembles johnsongrass in winter.

Purpletop is a perennial, warm-season, native - 36 to 60 inches tall.

Fair grazing for both livestock and wildlife.


Prefers shady, woody spots and sandy soil.
