Quick facts for kidsCirsium neomexicanum
This plant is native to the southwestern United States and northwestern Mexico, particularly the Mojave and Sonoran Deserts. It has been found in California, Nevada, Arizona, Sonora, Utah, Colorado, New Mexico, and Texas.
Cirsium neomexicanum is a tall plant, routinely exceeding 2 metres (6.6 ft) in height. It erects a stem which may have webby fibers and long, stiff spines. The sparse leaves are greenish-gray, hairy, and very spiny.
Atop the mainly naked stems are inflorescences of one or more large flower heads with rounded bases and phyllaries covered in long, curving spines. The largest heads may be up to 5 centimeters (2 inches) in diameter. They are packed with white or lavender disc florets but no ray florets.
The fruit is a flat brown achene with a long pappus which may reach 2 centimeters long. Unlike many other thistles, this species tends not to be a troublesome noxious weed.
