DESCRIPTION:
Purple nutsedge is a perennial weed in the sedge family plant that superficially
resembles grass. Leaves are V-shaped in cross section and arranged
in sets of three at the base. Stems are triangular in cross section.
Purple nutsedge grows mainly from tubers or "nutlets" formed
on creeping underground stems, mostly in the upper foot of soil. Purple nutsedge
can be distinguished from yellow
nutsedge by
its tubers or “nutlets.” Tubers of purple nutsedge are
produced in chains, with several on a single
creeping underground stem, while those of yellow nutsedge are produced singly on an underground stem. Purple
nutsedge flowers have a reddish tinge. Purple nutsedge resembles
green
kyllinga,
but green kyllinga has no underground tubers and has green rather
than reddish flowers.
