Giant Reed (Arundo donax L) is an invasive plant species found in the Southwest. This plant originally came to the U.S. from India in the 1820s.
Giant Reed, also known as arundo grass, elephant grass, Spanish cane, wild cane, and oboe cane, is a 20-foot perennial that clogs up stream beds. Giant Reed has become a problem in Sabino Canyon; it blocks the stream and crowds out native species.
