Sacramento Mountain Thistle Cirsium vinaceum

Native Specialist-bee host

Sacramento Mountain Thistle is a perennial wildflower native to the lower 48 states. A host for pollen-specialist native bees.

More about this plant

Cirsium vinaceum is a rare species of thistle known by the common name Sacramento Mountains thistle. It is endemic to Otero County, New Mexico, in the United States, where it is known only from the Sacramento Mountains. The plant can be found in six canyon systems in a southern section of this mountain range spanning about 32 kilometers. It is rare because it is limited to a specific type of mountain wetland which is both naturally uncommon and threatened by a number of forces. The plant was federally listed as threatened in 1987.

❧ Caterpillar hosts ~29 caterpillar species

Cirsium supports ~29 caterpillar species.

Native butterfly & moth caterpillars are the base of the terrestrial food web — most songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is a moderate genus.

✦ Bees specialist-bee host

Specialist native bees depend on it.

Some native bees are pollen specialists (oligolectic) — they raise young only on pollen from particular plant genera. Cirsium is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.
