This is a wildflower endemic to California and considered a Critically endangered species on the state and national level.

[1] The last remaining native populations are on the grasslands near Lawrence Livermore National Laboratory in Alameda County, California.

[2][3] This fiddleneck has low reproductive output; it produces few seeds per plant.

Also, processes like recombination can produce extremely unfit individuals, and inbreeding depression is a risk for both self-compatible and self-incompatible plants.

[5] This fiddleneck is also sensitive to habitat; it grows on sedimentary loam in mesic areas of its range.
