Tundra plants are small -- usually less than a foot high -- for four reasons. The soil lacks the nutrients of richer soils in other ecosystems that are filled with organic material. ... Smaller plants are more protected from cold and winds. Roots also are short and grow sideways, as they cannot penetrate the permafrost.

The tundra is a cold, harsh, dry ecosystem found in the Arctic, where it is known as Arctic tundra, and on mountain tops, where it is alpine tundra. Snow-covered for all but a few months, tundras experience harsh winds, even in summer. Soil is scant, and plants growing in the tundra cling to life with a series of important adaptations including size, hairy stems and ability to grow and flower quickly in short summers. Some plants grow with very little or no soil. Barren in the winter, the tundra in summer is awash with tiny alpine flowers that bloom in abundance; the landscape is green and lush with moss, lichens, sedges, grasses and dwarf shrubs.

Tundra plants are small -- usually less than a foot high -- for four reasons. The soil lacks the nutrients of richer soils in other ecosystems that are filled with organic material. The plants’ short statures help them absorb heat from the dark soil, which helps keep them from freezing. Smaller plants are more protected from cold and winds. Roots also are short and grow sideways, as they cannot penetrate the permafrost. These plants tend to grow in clumps; clumping offers protection from the cold and from wind-driven particles of ice and snow. Examples of small tundra plants include Arctic crocus, lousewort, heather and cress.
