GROWTH HABIT: A native perennial warm-season plant reproducing by seed and root systems. Woody nature but rarely grow to heights over 18 inches.
LEAVES: Alternate, narrow, and untwisted, 1 to 1 1/2 inches long and are green with smooth margins, slightly rolled to the center and are located on the upper parts of the plant.
STEMS: Grow new from the crown each year, not from old growth. Stems are close together, stiff, and somewhat resinous.

OTHER: Broom snakeweed is a common poisonous plant which is most toxic during leaf formation. Most losses occur in cattle and sheep as abortions. Weak calves and lambs are common during times when pasture is scarce and broom snakeweed is eaten. Pastures are not properly utilized when this weed is found intermixed with the grasses. Control of this species can be attained with herbicides.
