Plant Information
Noteworthy Characteristics 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. Problems No serious insect or disease problems. Rust may be troublesome in humid climates, though this cultivar reportedly has good resistance. Crown rot may occur in moist, poorly drained soils Height: 2.00 to 3.00 feet Spread: 2.00 to 2.50 feet Bloom Time: June Bloom Description: Bluish brown Sun: Full sun Water: Dry to medium Tolerate: Deer, Drought, Black Walnut, Air Pollution
