Abstract:
Catchweed bedstraw
(Galium aparine L.), also called
bedstraw or cleavers, is a native
annual with weak, climbing,
or twining stems, up to 6 feet
long (figure 1). Whorls of six
to eight narrow single-nerved
leaves are attached to square
stems (figure 2). Both stems
and leaves have short backward-
turning bristles that
cause the plants to cling to
other objects.
