Cirsium neomexicanum Gray
(New Mexico Thistle)


Family: Asteraceae

Status: Native

Synonyms:
Carduus neomexicanus (Gray) Greene
Cnicus ochrocentrus (Gray) Gray

Cirsium neomexicanum is our most common roadside thistle in the Gila Wilderness. It has reflexed outer phyllaries and a pale pink-purple almost spherical inflorescence that blooms early in the spring. The leaves are spiny. Cirsium neomexicanum branches like a candelabra from a point about 2/3 to the top when it has not been disturbed or mowed. The similar Cirsium ochrocentrum var. martinii is slightly darker in color and branches from a lower point giving it a more spreading appearance. Cirsium neomexicanum is found at lower to middle elevations in the Gila.
