An introduced weed that now can be found in the United States from California to Florida and in Hawaii, as well as sporadically in the Northeast and Midwest.
This is a perennial weed that reproduces from seeds, and will re-grow from the roots if the foliage dies back or is removed. It is a clump-forming plant that grows in many habitats, including landscape, roadsides, and disturbed areas.
Numerous thin stems arise from the base of the plant and grow to 3 feet in height. Stems are narrow and tend to recline, giving the plant a drooping, spreading, or sprawling posture. Leaves are very wide at the base, with long hairs at this point, and may be up to 1 foot in length. The flower head is a compact, elongate spike around 6 inches in length, with the flowers arranged closely along it.
Characteristicts Important to Control:
A systemic herbicide will be needed to control this perennial weed.
