Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. There are many different plant species and taxa that grow as a plant community in these alpine tundra. [1] These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [2]
[4]: 224 Many Sierra Nevada alpine plants have reddish or whitish leaves to protect them from damage from intense ultraviolet radiation in the alpine zone. [5]: 17 [11] Fleshy roots and underground organs store food in the form of starches and sugars, allowing the plant to quickly grow when snow melts. [5]
It is found in the central area of the southern Appalachian mountains, mainly on rocky outcrops of limestone or mafic rocks. [71] [72] Eriogonum alleni [73] Eubotrys recurva- mountain fetterbush. It is common at higher elevations of the southern Appalachian mountains. [74] [75] Eutrochium steelei - Appalachian Joe Pye weed. [76] [77]
Some plants with a broader altitudinal range are found listed in their predominant habitat elevation. All the plant species listed are native to the Sierra's foothills, valleys, and mountains. In addition some are also endemic to here and elsewhere within California – (ca-endemic) ; and some are further endemic to and only found in the Sierra ...
The soil there is frozen from 25 to 90 cm (10 to 35 in) down, making it impossible for trees to grow there. Instead, bare and sometimes rocky land can only support certain kinds of Arctic vegetation, low-growing plants such as moss, heath (Ericaceae varieties such as crowberry and black bearberry), and lichen.

The herbaceous plants need to flower and produce their seeds quickly during the short, frost-free period of summer. [3] Flora includes cushion plants , grasses, willows, and sedges . [ 9 ] The macrolichen flora in the Sierra Nevada alpine zone is not well developed as compared to neighboring alpine zones in the Rocky Mountains and mountains of ...
