    Starrush Whitetop is a perennial native throughout Florida. This plant has long thin grass-like leaves and grows to 24 inches tall. Flowers consist of small cone-shaped spikelets with three to six long, thin bracts that appear just below each spikelet. The 3 to 6 inch long petal-like bracts are white with green tips that abruptly bend downward. Spreading to form dense colonies, Starrush Whitetop is found in habitats of moist pinelands, wet prairies, and ditches.

    Grows in moist, boggy/swampy conditions, in ditches, or on the banks of creeks or rivers.

    This can be seen growing prolifically in sections of the Alligator River in North Carolina.

    Common in moist or wet open areas or thin woods along the coastal plain from Virginia to Texas, White Star Sedge looks like a grass with daisy-like flowers with long, drooping, pointed petals. The "flowers" are composed of 5 or 6 conspicuous drooping white bracts or leaves surrounding inconspicuous flowers on 1 to 2 foot stems. Whitetop Sedge can be fairly aggressive in moist soil with sun or part shade. Drier sites will slow the spread. The white "flowers" are effective all summer into fall.
