Muir's raillardiopsis

Carlquistia muirii

Also called Muir's Tarplant

Muir's raillardiopsis is a rare, rhizomatous perennial herb from California's Sierra Nevada and Santa Lucia Mountains, grown mainly by botanists and native plant enthusiasts rather than as a garden plant. It is a wild-type species with little cultivation history, so care is inferred from its native habitat.

About

Carlquistia is a rare North American genus of flowering plants in the family Asteraceae containing the single species Carlquistia muirii. Formerly named Raillardiopsis muirii, the plant was reexamined in the 1990s and moved to a new genus of its own, separate from similar and closely related genera, such as Madia. Common names for the species include Muir's tarplant, Muir's raillardiopsis, and Muir's raillardella.

This plant is related to the silversword alliance of Hawaiian plants.

Where it grows

Carlquistia muirii is endemic to California. It has a discontinuous distribution, occurring in the southern Sierra Nevada (Fresno, Tulare, and Kern Counties) and on the other western side of the San Joaquin Valley around the Ventana Double Cone in the Santa Lucia Mountains of Monterey County.
