Polar grass (Arctagrostis latifolia) is a hardy perennial species that’s mastered survival in Arctic and subarctic regions through remarkable adaptations. It grows in dense tufts reaching 2-4 inches tall, featuring distinctive blue-green blades with waxy coatings and an extensive underground rhizome network extending up to 2 feet beyond visible growth. The plant’s sophisticated cold tolerance.. Plants have also adapted to the long winters and short, intense polar summers. Many Arctic species can grow under a layer of snow, and virtually all polar plants are able to photosynthesize in extremely cold temperatures. During the short polar summer, plants use the long hours of sunlight to quickly develop and produce flowers and seeds.
