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 ...
Raoulia rubra is a cushion plant belonging to the family Asteraceae and is found in the mountains of southern North Island and northern South Island, New Zealand. Its common name is scabweed. Although the whitish cushion can be two feet (60 cm ) wide it is only 25 mm (one inch) thick and looks like a lichen. The scattered tiny flowers are red. [1]
Yareta is an evergreen perennial with a low, mat-like shape and hemispherical growth form that grows to around 6 m (20 ft) in diameter. [3] The self-fertile, pink or lavender flowers are hermaphroditic and are primarily pollinated by small flies in the order Diptera, as well as a variety of other small insect species, including bees, wasps, and moths.
Phlox family (Polemoniaceae) perennials include dwarf phlox, or cushion phlox (Phlox condensata), which forms dense cushions plant with tiny branchlets only 1 inch (0.025 m) long, tiny leaves only 0.2 inches (0.0051 m) long and well adapted to resist the high winds, and flowers forming a nearly solid floral blanket of the underlying plant.
Colobanthus muscoides is a low-growing, moss-like flowering cushion plant in the family Caryophyllaceae, found on islands in the south-western Pacific Ocean, especially in the subantarctic region. The specific epithet comes from the Latin muscus (moss) and -oides (resembling), with reference to its growth habit.
The flowers are small, solitary, white, and tubular, sitting directly on top of the foliage. [5] The plant can often be mistaken for the vegetatively similar cushion plants Abrotanella forsterioides and Donatia novae-zelandieae, however D. minimum is distinguished by its lack of a hairpoint on the leaf tip or hairy leaf axils.

It can have white flowers which grow at the end of stems which are 0.2-2mm long. It generally flowers or fruits from October to May. [3] S. archeri can be distinguished from Schizacme montana and other cushion plants by its leaves. S. archeri has leaves that are circular and stacked together unlike other cushion plants.
