Erigeron rhizomatus
Also called Zuni Fleabane
Rhizome fleabane is a rare, federally threatened perennial daisy from a few isolated sandstone outcrops in western New Mexico and eastern Arizona. It is not a garden plant, and it is hard to cultivate because it needs selenium-rich, eroding rock.
Erigeron rhizomatus is a rare species of flowering plant in the family Asteraceae known by the common names Zuni fleabane and rhizome fleabane. It is native to western New Mexico and eastern Arizona in the United States. It is a federally listed threatened species.
Erigeron rhizomatus was thought to be a New Mexico endemic until 1999, when some plants were found over the border in Arizona. These are located in the Chuska Mountains on the Navajo Nation, and they occur in 15 populations that make up one metapopulation. The two previously known metapopulations in New Mexico are composed of 24 populations in the Zuni, Datil, and Sawtooth Mountains. These three metapopulations are geographically isolated from each other but are still similar in morphology.
Erigeron rhizomatus grows in selenium-rich sandstone substrates that originate in the Baca and Chinle Formations. It occurs in barren outcrops of eroding red or grayish rock that may have slopes of up to 40 degrees. Nearby plants include four-wing saltbush (Atriplex canescens), mountain mahogany (Cercocarpus montanus), rubber rabbitbrush (Ericameria nauseosa), oneseed juniper (Juniperus monosperma), Colorado pinyon (Pinus edulis), and Gambel oak (Quercus gambelii).
