What can grow in the tundra?

Some plants that grow in the tundra include short shrubs, sedges, grasses, flowers, birch trees and willow trees. Cushion plants, which, also grow in the tundra, are types of plants that grow low to the ground in tight places.

Why is it hard to live in the tundra?

The Arctic tundra is characterized by its layer of permafrost or permanently frozen subsoil that contains mostly gravel and nutrient-poor soil. This prevents plants with deep root systems from taking hold. ... Few if any reptiles and amphibians live in the tundra due to the extremely cold conditions.
