Acanthus, << uh KAN thuhs, >> is a group of shrubs or herbs that are found chiefly in Asia, Africa, and southern Europe. They spread from underground stems and sometimes become pests. The flowers vary in color from white to purple and develop on rigid spikes. The large leaves have many narrow, pointed lobes.
Acanthus plants prefer rich soil and some shade, and can live with little water. A common acanthus species (kind) of the southwestern United States is the desert honeysuckle.
In architecture, acanthus refers to a leafy decoration that was popular in Greek and Roman times. The design at the top of the Corinthian column is an example of acanthus. See Column .
