A perennial weed reproducing by seeds and short rhizomes. Mature plants tend to form thick clumps with stems and flower heads up to 6 feet tall. One of more than a dozen species of “bluestem” in the southeast. May be found in many habitats, from dry open fields to wet drainage ditches and roadsides.
Mature plants are up to 6 feet tall with several strong, erect stems clumped together. Early growth is a bluish green, changing to straw-colored upon maturity. Leaf sheaths are flattened and a short ligule is present.
Flower heads are composed of many side branches off the main stem, and individual flowers are elongate and with long, silky hairs, giving them a very full appearance.
Characteristicts Important to Control:
A combination of pre and post-emergent herbicides may be needed, with a systemic possible to kill the rhizomes in the soil.
