DESCRIPTION:
Large crabgrass is a summer annual weed, but new seedlings may begin
to appear as early as February in warmer areas of California. The
crabgrass ligule is stiff and papery and there are no auricles.
There may be stiff, white hairs on the sheath and edges of the leaf
but there are none on the ligule. The flowers are held in 3 to 7
slender fingerlike branches on the end of the flowering stem. The
large crabgrass seedling has rather wide leaves that are covered
with coarse hairs. Leaves unroll as they grow out of the center.
