Helictotrichon sempervirens is an easy-to-grow, clumping, cool season ornamental grass. It forms a bristly but graceful 2 foot mound of steely-blue foliage that is offset by an additional foot of golden-brown feathery flower stems in midsummer. Drought tolerant, the blue color of Blue Oat Grass is more intense in dryer soil and full sun. Evergreen in mild climates and semi-evergreen for colder regions. Use as a specimen plant in the border and rock garden. Perfect fit for the Modern Design and low maintenance gardens as well.
How tall and wide does Blue Oat Grass grow?
It grows 2–3 feet tall and about as wide, forming compact, symmetrical clumps that stay tidy without spreading.
When does Blue Oat Grass bloom?
It blooms in late spring to early summer with tall, tan flower spikes that rise above the foliage, adding graceful movement and contrast.
What kind of sunlight and soil does it prefer?
Blue Oat Grass thrives in full sun and well-drained soil. It prefers dry to moderately moist conditions and performs best in cooler climates.
How much water does it need?
Water regularly during the first growing season to establish deep roots. Once mature, it’s drought-tolerant and thrives with minimal watering.
