Grazing North Texas: Annual Broomweed

By Tony Dean

Annual broomweed can be a real nuisance to North Texas ranchers when we have a “broomweed year.” Broomweed, along with Western ragweed, are two of the most troublesome weeds that plague our grazing lands. Both of these forbs, however, can benefit wildlife.

Annual broomweed, sometimes called common broomweed or prairie broomweed, is a robust annual forb found in almost every part of Texas. It normally grows from a single stem, but if damaged when young, the plant can form multiple stems.

As annual broomweed matures, the stem becomes very rigid and erect and the plants develop a rounded tree-shaped top. Under good growing conditions mature plants can reach three feet in height and two to three feet in diameter of the top.
