Some Arctic plants grow close to the ground as cushion plants, which keep the plants close to the warm soil and shield the tender central growing shoot. Arctic plants limit their height to be below the snow level. Plants that protrude above the snow are subject to strong winds, blowing snow, and being eaten by caribou, muskox, or ptarmigan.
The compact growth form of cushion plants reduces air flow over the surface of the epidermis, reducing the rate of water loss. Additionally, many cushion plants have small and fleshy leaves which reduce the surface area of the plant, which reduces transpiration and conserves water. In alpine environments well above the tree line, cold is a ...

There are about 60 species of Arctostaphylos, ranging from ground-hugging arctic, coastal, and mountain shrub to small trees up to 6 m (20 ft) tall. Most are evergreen (one species deciduous ), with small oval leaves 1–7 cm (0.4–3 in) long, arranged spirally on the stems.
