A perennial bushy warm season plant that reproduces from seeds and from the roots. The foliage, in particular, contains toxic substances that can cause serious problems in livestock, including loss of vigor and aborted fetuses. In cooler climates the above ground stems and leaves die, with new growth occurring from the crown and roots each year.
A common plant found along roadsides and in natural areas, but needing removal in grazing areas. Physical removal may be effective and can eliminate seed production, but a systemic herbicide capable of killing the roots will be needed to eliminate the plants.
