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]
