In phytogeography, concerned with the geographic distribution of plant species, floristic provinces are used. The Sierra Nevada are primarily within the California Floristic Province, with the Rocky Mountain Floristic Province to the north, the Great Basin Floristic Province to the east, and Sonoran Floristic Province to the south.
The western and eastern Sierra Nevada have substantially different species of plants and animals, because the east lies in the rain shadow of the crest. The plants and animals in the east are thus adapted to much drier conditions. [4] The altitudes listed for the biotic zones are for the central Sierra Nevada.
Annuals plus woody shrubs constitute only about 6% of the number of Sierra Nevada alpine floral species. [1] Sierra gentian (Gentianopsis holopetala), in the gentian family (Gentianaceae), is an erect or sprawling annual or perennial, growing in wet meadows from 6,000 to 13,000 feet (1,800 to 4,000 m) elevation.

A botanist gently strokes the pollen of endangered wildflowers with a paintbrush as she tries to reenact nature inside a small greenhouse in the shadow of the Sierra Nevada. It's part of a lithium ...
The Sierra Nevada are home to half of the vascular plant species of California, with 400 species that are endemic to the region. [16] Like many mountain ranges, the plant communities of the Sierra group into biotic zones by altitude, because of the increasingly harsh climate as elevation increases. [19]
