New Mexico thistle

Cirsium neomexicanum

Summary ⁸

Cirsium neomexicanum is a North American species of thistle known by the common names New Mexico thistle, powderpuff thistle, lavender thistle, foss thistle and desert thistle.

Description ⁹

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.
