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. When found in heavy stands, these mature plants can sometimes form almost a full canopy over the land.
Annual broomweed is in the sunflower family. In late summer, tiny yellow flowers appear on the ends of the many branches at the top of the plant. Heavy stands can cause pastures to take on a yellow appearance over many acres during late summer months. At the time of flowering, many of the leaves have dropped from the plant, leaving the stalk and branches bare except for the yellow flowers. To read more pick up the March 2016 issue of NTFR.
