Helictotrichon, or alpine oatgrass, [2] is a genus of perennial flowering plants in the grass family. [3] [4] [5] [6] The genus name comes from the Greek heliktos meaning twisted, and trichos meaning hair, referring to the shape of the awn. [7]

Most of the species are native to Africa and Eurasia with a few species in North America. Helictotrichon sempervirens is widely cultivated as an ornamental. [8] [9] [10]
