Hesperostipa comata
An unmistakable bunchgrass of Alberta's dry prairie — long twisted awns (up to 15 cm) trail from sharp-tipped seeds in a dramatic fringe effect, like thread from needles. The sharp seeds can work into livestock wool and pet fur, posing veterinary risks. Exceptionally drought-tolerant.
