About Eryngium articulatum Hook.
Eryngium articulatum Hook. is a species of flowering plant in the carrot family, commonly known as beethistle and jointed coyote thistle. It is native to the northwestern United States, ranging from California to Idaho, where it grows in marshes and riverbanks. This is a sturdy, branching perennial herb with rounded, bare stems that can grow to over one meter in maximum height. A small number of sparse, sharply serrated leaves grow at the nodes and branching points along the stem. At the top of the stem sits a rounded to egg-shaped flower head that looks superficially like a thistle, mostly because of its spiky texture and lavender color. The flower head is fringed with up to 17 spiny, toothed, pointed bracts, each reaching about two centimeters long. Every flower head is densely filled with small lavender flowers.
