Helictotrichon sempervirens
Blue oat grass is a reliable, vigorous ornamental grass species, growing in clumps of grassy foliage. Its narrow leaves form an attractive contrasting texture in the garden, with a color changing from green to blue in the summer. In the late summer and fall, blue oat grass bears panicles of spike-like flowers that are silvery-gray in color. It's an excellent choice for low-maintenance gardens, and is tolerant of drought and windy conditions. It also offers good year-round interest, since the foliage remains attractive even when not in bloom. Blue oat grass is a great addition for any garden looking for an easy-care grass.

watering
Blue oat grass needs to be watered deeply and infrequently. Generally speaking, it should only be watered once every 7–10 days, or when the top 3 to 5 inches of soil is dry. It is important not to over-water or allow the soil to become soggy as this can cause root rot. Blue oat grass likes moist but not wet soil, so when you water it, water slowly and deeply in order to provide the deep hydration it needs. Additionally, in the warmer months, it may need to be watered every 5–7 days.
sunlight
Blue oat grass (Helictotrichon sempervirens) grows best in full sun, which means it should receive at least 6 hours of direct sunlight per day. It prefers to grow in sunny locations with well-drained soil. Because it is a grass, it is also important to make sure that the soil is not overly wet for too long, as this can lead to disease and other problems. It is best to plant blue oat grass in the spring or fall, as these are the times when the soil is warmest and the water levels are controllable. It is also important to note that blue oat grass can be invasive, so it is important to practice maintenance regularly to make sure it doesn’t spread too far.
pruning
Blue oat grass should be pruned in early spring when new growth begins to appear. Prune the grass back by 1-third to 1-half its entire height. This will encourage fresh, new growth and prevent the grass from becoming too tall and gangly. After pruning, fertilize the blue oat grass to promote healthy growth.
