What are alpine and rock garden plants?
Alpines refer to plants that grow above the tree-line, generally from higher elevations. Alpines are exposed to various conditions including extreme moisture levels, low nutrient levels, wide temperature ranges, shifting substrates, grazing by animals, exposure to wind, and high light levels. Adaptations include small size, shapes that minimize exposure to the harsh wind and cold, dormancy under snow, mineral encrustation and crystal growths, foliage coloration, extensive roots to cling to mountain sides or seek water and nutrients, hairs for condensation, or spiny growths to deter grazing. It is important to note that there are many permutations of alpine and subalpine climates.
