It is endemic to California, where it grows along the coastline in the southern half of the state. Taxonomically, this species is a highly variable complex of polymorphic and polyploid plants, closely related to numerous neighboring species such as Dudleya farinosa, Dudleya greenei and Dudleya palmeri. It is delimited from neighboring species on an arbitrary basis of distribution and chromosome number, and may not be immediately separable from the other species it approaches.
Taraxacum is a large genus of flowering plants in the family Asteraceae, which consists of species commonly known as dandelions. The scientific and hobby study of the genus is known as taraxacology. The genus is native to Eurasia and North America, but the two most commonplace species worldwide, T. officinale and T. erythrospermum, were introduced from Europe into North America, where they now propagate as wildflowers. The plant thrives in temperate regions and can be found in yards, gardens, sides of roads, among crops, and in many other habitats. Both species are edible in their entirety and have a long history of consumption. The common name dandelion is also given to specific members of the genus.

It is widespread across much of central and western Canada and the western and central United States from Ontario west to British Columbia and south to Louisiana, Texas, and California. Most of the known populations are on the Great Plains; populations west of there may well represent naturalizations.
Krigia dandelion, known as potato dwarfdandelion, is a North American species of plants in the family Asteraceae. It is native to the southeastern and south-central United States, from the Florida Panhandle to Texas and north as far as Kansas, southern Illinois, and Maryland
