DESCRIPTION:
Yellow nutsedge is a perennial weed in the sedge family that superficially
resembles a grass. Leaves of sedges are thicker and stiffer
than
most grasses and are V-shaped in cross-section and arranged in
sets of three at the base; grass leaves are opposite in sets
of two.
Stems are triangular in cross-section whereas grass stems are hollow
and round. Yellow nutsedge can be distinguished from purple
nutsedge by its tubers or "nutlets." Tubers of yellow nutsedge
are produced singly on rhizomes, mostly in the upper foot of soil,
while purple nutsedge tubers are produced in chains, several on
a single rhizome. Yellow nutsedge has light brown flowers and
seed.
Yellow nutsedge resembles green kyllinga
but green kyllinga has no underground tubers and
has green rather than yellow flowers.
