Pamir alpine desert and tundra

A part-shade planting with shrub structure and low foliage contrast.

The Altai alpine meadow and tundra ecoregion crowns the high Altai Mountains where the borders of Russia, Kazakhstan, China, and Mongolia meet, sitting above the conifer treeline in Central Asia's northernmost ranges. Above the treeline, low-alpine meadows mix grasses such as Stipa feather grass and clumping Festuca with herbaceous wildflowers, dwarf birch (Betula rotundifolia) in wetter northern areas, and sedge-meadows of Kobresia and Carex, giving way to sparse moss, lichen, and creeping cushion plants on the highest plateaus. The climate has a distinctly arctic character, with brief temperate summers, extreme cold winters, and a tundra-like regime where no month averages above 10 degrees Celsius. The ecoregion supports apex predators including snow leopards, lynx, gray wolves, and wolverines, with the vulnerable Altai argali wild sheep serving as a flagship species. Higher slopes also host hardy ornamental and medicinal natives such as dwarf rhododendrons, saxifrage, rhodiola, juniper, and honeysuckle.

The Central Tibetan Plateau alpine steppe is a vast high-elevation ecoregion stretching across the Tibetan Plateau of China, reaching east to Qinghai Lake and extending into adjacent parts of India, with land ranging from roughly 3,500 meters to nearly 6,000 meters in elevation. Vegetation is sparse, typically covering only about a fifth of the ground, and is dominated by sedges such as Kobresia and Carex together with purple feathergrass (Stipa purpurea), alongside cushion plants and alpine forbs in more stable, moister soils; there are no trees. The climate is cold and arid, classified as a tundra (Köppen ET) regime with no month averaging above 10 degrees Celsius, and precipitation declining from the northwest toward the southeast. Because the harsh conditions are largely unsuited to agriculture, the ecosystem remains relatively intact and still supports roaming herds of wild ungulates, including the migratory Tibetan antelope, argali, Tibetan wild ass, and the endangered Przewalski's gazelle, along with predators such as the snow leopard and gray wolf. For gardeners, several alpine genera native here, including Saussurea, Leontopodium, and Arenaria, are familiar in cold-hardy rock and cushion-plant horticulture.

The Eastern Himalayan alpine shrub and meadows ecoregion threads along the high Himalaya across five countries, reaching eastward from central Nepal near the Kali Gandaki River through Bhutan and India's Arunachal Pradesh to northern Myanmar and Tibetan China. Nested between the treeline near 4,000 meters and the snowline around 5,500 meters, it shifts from low alpine shrublands dominated by stunted, twisted rhododendrons into open meadows that burst with brightly colored flowers each spring and summer. Characteristic meadow genera include Meconopsis, Primula, Gentiana, Saxifraga, Androsace, Leontopodium, and Pedicularis. The climate is sharply seasonal: the May-to-September monsoon delivers heavy rainfall, with much drier rainshadow pockets, summer temperatures averaging about 20 degrees Celsius, and winters dropping below freezing. Renowned for exceptional botanical richness with over 7,000 plant species recorded, it shelters snow leopards, blue sheep, Himalayan tahr, and takin. Many of its native ornamentals, especially the blue poppies (Meconopsis), rhododendrons, and primulas, are treasured by alpine and rock gardeners.

The Ghorat-Hazarajat alpine meadow occupies the high mountainous interior of central Afghanistan, fanning out westward from the capital city of Kabul at its eastern point. Its vegetation is a mix of thornbush meadows and alpine grassland, with Himalayan juniper shrub thickets and herbs and flowering plants including sainfoin, Astragalus, Cousinia, and Artemisia, set across elevations that climb from roughly 1,248 to 4,868 metres. The climate is cold and dry with large seasonal swings and warm summers, giving a mean annual temperature of about 3.2 degrees Celsius and average annual precipitation near 416 millimetres. The ecoregion is best known for the critically endangered Afghan brook salamander (Paghman mountain salamander), which clings to cold high-mountain streams within a potential range of less than 10 square kilometres; less than 1 percent of the region is officially protected, with Band-e Amir National Park, famed for its travertine lakes, the main reserve. For gardeners, several cold-hardy native genera that thrive here, including Astragalus and Artemisia, are familiar in dryland and rock-garden plantings.

The Hindu Kush alpine meadow spans the high Hindu Kush range across northern Afghanistan, northwestern Pakistan, and southern Tajikistan, a steep, mountainous landscape whose terrain mostly sits between 3,000 and 4,000 meters and climbs to peaks above 6,500 meters. Roughly half of it is bare rock or gravelly soil with sparse vegetation, while the remainder carries subalpine thickets, cushion shrublands, and alpine meadows of grasses and herbs, including the genera Primula, Sibbaldia, Astragalus, and Onobrychis. The climate is cold and continental with large seasonal swings, much of the high-elevation precipitation falling as snow. Over 200 vertebrate species have been recorded, with the markhor as the flagship species alongside Siberian ibex, argali, and the endangered Kashmir musk deer, yet the ecoregion currently has no protected areas. For gardeners, the native alpine flora here includes cold-hardy ornamental cushion and rock-garden genera such as Primula and Sibbaldia.

The Karakoram-West Tibetan Plateau alpine steppe is a vast high-elevation grassland ecoregion centered on the Karakoram Range west of the Himalaya, spanning portions of Pakistan, India, China, and Afghanistan within the upper Indus catchment. Most of it is open steppe of Stipa and Festuca grasses and forbs on slopes above 3,000 meters, while valley bottoms hold dense thickets of woody plants such as sea buckthorn (Hippophae rhamnoides), willow, tamarisk, and wild rose, with relict juniper forests in remote pockets. The climate is cold and arid, with annual precipitation ranging from roughly 200 to 900 millimeters, about 90 percent of it falling as snow, and extreme topographic relief where river channels below 2,000 meters sit beneath massifs exceeding 8,000 meters. Its flagship species is the woolly flying squirrel, and its rich community of wild sheep and goats, including Marco Polo sheep, argali, markhor, urial, and ibex, supports the snow leopard, with protection afforded by parks such as Hemis, Khunjerab, and Deosai. Hardy native ornamentals here include the showy larkspur Delphinium cashmerianum, shrubby cinquefoil (Potentilla fruticosa), and Rosa webbiana.
