DESCRIPTION:
Johnsongrass is one of the most troublesome of perennial grasses. It reproduces
from underground stems and seeds. The mature plant grows in spreading,
leafy patches
that may be as tall as 6 to 7 feet (1.8 - 2.1 m). Leaves have a prominent
whitish midvein, which snaps readily when folded over. The flower head
is large,
open, well-branched, and
often reddish tinged. Underground stems are thick, fleshy, and segmented.
Roots and shoots can rise from each segment. The ligule consists of a
fringe of dense, fine hairs.
