Weed Type: Grassy Weeds & Sedges

Grassy annual weed with alternate narrow leaves. Produces flowers in open clusters that are blueish to purplish in color. Stems are creeping and form a mat when highly populated. Often found growing in moist sites.

Perennial sedge with densely tufted leaves. Leaves are flat, smooth and bright green in color. Seedhead produces clusters of globe-like seeds at the top of stems that are spiky in appearance.

Grassy annual weed with tough clump type growth. Center of plant is whitish to silver in appearance. Produces a seedhead with multiple finger. Does not mow well due to tough nature.

Upright growing cool-season annual grass that grows in clumps. Seedheads with long bristles that resemble a fox tail. Reproduces by seed.

Perennial sedge with dark, glossy leaves that taper abruptly. Seedheads purple to reddish brown in color at the end of triangular stems. Produces underground tubers that are hairy and oblong. Spreads rapidly primarily by tubers.

Warm season annual grassy weed with creeping, prostrate growth habit. Leaves are smooth, flat, and wide. Seedhead branches spreading like “signal flags” with seeds on underneath side. Reproduces by seed.

Grassy perennial weed that grows in clumps. Leaves are long, flat and rounded at tip. Produces narrow seedhead that is often black in appearance due to a fungus that infects the seeds. Reproduces by seeds.

Tufted and clumped with light green to whitish spikelets. Reproduces by seed. Winter annual. Leaf blades smooth. Leaf tip boat shaped.

Warm-season annual grassy weed that grows in a loose clump. Leaves are mostly smooth to slightly rough. Stems often reddish as base. Produces a seedhead with spiky, spiny burs. Prefers sandy soils. Reproduces by seed.

Stems triangular or three sided. Often grows in a clump. True annual weed. Seedheads at top of bare stem and are flat spikes with toothed edges. Emerges in late spring/summer. Prefers moist sites but can survive dry conditions.
