Alpine flower heads face East throughout the day, instead of following the sun like Helianthus do, as an adaptation from strong afternoon thunderstorms rolling out of the west. characterized by cold nights as well. Alpine tundra plants have special adaptations to cope with the harsh conditions. Features that might not come immediately to mind are low carbon dioxide and oxygen levels, high UV levels, summer frosts, poor soil, drought and low pollinator diversity. Alpine plants have adapted in different ways to survive low temperatures. Some plants make chemicals to stop them from freezing. This short description of the natural conditions in alpine environments makes it clear that alpine life is a highly complex interactive system that has evolved over millions of … Examples of mound-forming alpines include saxifrages and moss campion, Some examples of mat-forming alpines include creeping baby's-breath, creeping speedwell and creeping phlox. The word alpine comes from the Latin alpes which means ‘high mountain'. They don’t grow stems, leaves, flowers and fruite each season. This is a trick that several species above the tree line use, including saxifrages. They can be active at temperatures much lower than other insects can tolerate. Plants of the same species often grow near each other in clusters in the tundra. This can lead to above freezing temperatures around the plant even when the air temperature is below freezing. The short growing season and cool soil temperatures results in the slow decomposition of organic matter hence many nutrients become unavailable. Most are slow-growing perennials. The remarkable cushions of vegetable sheep (Raoulia and Haastia species) have adapted to avoid drying out on rock at high altitude. As you can see from the climate graph for Kuwait, plants and animals in the desert have to cope with very little water. Cushions at higher elevation are typically smaller and denser. They may not be as flamboyant as say, begonias, dahlias and roses, but the variable forms and textures exhibited by alpine plants and their often small, but exquisite blooms, I can't resist.

Of course this has its drawbacks when growing some of these plants in our gardens, as they literally burn-up under typical temperate summer temperatures. Plant and animal adaptations in the desert. This results in slow growth rates of arctic-alpine plants and their low requirements for extra fertilizing. Similar adaptations help plants, algae, fungi, and lichens survive in both the Arctic and Antarctic. This was true regardless of the form of nitrogen supplied (nitrate, ammonium nitrate, or organic nitrogen). Plant books and catalogs warn you about over watering Alpine plants. The plant's form is well adapted to trapping warm summer air within its body to extend the time during which it can photosynthesize. Small leaves help prevent evaporation of precious moisture and staying low to the ground – preferably behind a rock or in a dimple – works as a protection against the harmful effects of the wind. The tiny hairs on the plant collect thousands of air bubbles which protect the flower from burning in the sun, drying out, or freezing in the harsh alpine environment.
