Origin:

Native to the southeast states of the United States, and now occurring throughout most of the eastern half of the U.S. and into Mexico.

Biology:

An annual or biennial plant that reproduces from seeds. This spiny weed is common along roadsides and in disturbed areas.

Identification:

Mature plants can be over 4 feet in height, growing erect with multiple stems, and branching in the upper portions of the plant. The stems are smooth but have long, sharp spines sporadically along them. The stems are stiff and fibrous. Leaves also have spines along their deeply lobed margins. The mid-vein is thick and prominent, and lateral veins are a lighter color. All plant parts exude a white sap when broken. The large white flowers have 6 or more large petals, and the reproductive parts in the center are prominent. The seed pod that forms is a large, spiny capsule that is egg-shaped and about 1 to 2 inches long.

Characteristicts Important to Control:

Physical removal is possible for small infestations, and a non-selective herbicide will be effective for larger problems.
