Centaurea calcitrapa is a species of flowering plant known by several common names, including purple starthistle and red starthistle.
It is native to Europe but is rarely found there, it is known across the globe as an introduced species and often a noxious weed.[1][2]
The species name calcitrapa comes from the word caltrop, a type of weapon covered in sharp spikes.[3][4]
The stems are hairless and grooved.[8] It sometimes takes the shape of a mound, and it is finely to densely hairy to spiny. The leaves are dotted with resin glands. The lowermost may reach a length of 20 centimeters and are deeply cut into lobes. The inflorescence contains a few flower heads. Each is 1.5 to 2 centimeters long and oval in general shape. The phyllaries are green or straw-colored and tipped in tough, sharp yellow spines. The head contains many bright purple flowers. The fruit is an achene a few millimeters long which lacks a pappus.
It flowers from July until September, and the seeds ripen from August to October.
