14 in stock



2 Gallon Pot. Helictotrichon sempervirens, commonly called blue oat grass, is a clump-forming, cool season, ornamental grass which typically grows 2-3′ tall (foliage clump to 2′ and flower stem brings total height to 3′) with a similar spread. Features very narrow (3/8″ wide), spiky, steel blue leaf blades (to 18″) which form a rounded, porcupine-like clump. Resembles blue fescue (Festuca glauca), but is significantly larger. Spikelets of bluish-brown flowers arranged in open, one-sided panicles arching at the tip appear on erect stems rising well above the foliage clump in June. Flower spikelets mature to a golden wheat color by fall.
