Blue Oat grass looks like a miniature water fountain, with its densely packed leaves gently spraying upward and arching back downward at the tips. This species displays spiky, blue-gray foliage that will draw your attention all season long.
In early summer, small, tan seed heads appear on tall stems held well above the foliage. In mild climates, this grass is evergreen; it is semi-evergreen in colder zones.
Blue Oat Grass adds a wonderful coarse element to rock gardens, coastal gardens, or dry hillsides.

The best place to plant Helictotrichon is a dry, sunny site. Once established, it will not require supplemental watering unless there is a drought. Trim back the old foliage to 3-4" in spring before the new growth emerges. Division is recommended every 3-4 years in spring to keep the plant looking fresh.
Container:
Trade 1 Gallon Container
When to Plant:
Late summer - fall or late winter - spring
Finish:
8-10 weeks
Notes:
Cool season grass. Grow cool at 55-65° F.
Container:
Premium 1 Gallon Pot
When to Plant:
Late winter to spring or fall
Finish:
8-10 weeks
Notes:
Cool season grass. Grow cool at 55-65° F.
Growing Temperature:
55-65° F
Holding Temperature:
40-50° F
Soil PH:
5.8-6.3
EC (What is EC?):
1.5-2.5 pour through method
Fertility:
Feed moderately at 75-100 ppm N at each watering during the cool growing season. Back off the rate during the summer when this cool season grass slows its growth rate. Avoid salt build-up and leach the soil once in a while during the summer months.
Vernalization:
Vernalization improves flower perfomance. Provide 8-10 weeks of temperatures below 40° F.
Pests & Diseases:
Clumps may die out in spots, or die out completely. This problem is often caused by one or more of the following factors: high salt levels in the media, too much irrigaton, or poor physical properties of the media.
Potting & Timing:
Plant bare root plants under cool tempereatures of 55-65 degrees F. Warm temperatures during transplanting can cause plant failure. Plants must form new feeder roots to support the evergreen tops. Warm temperatures can cause excessive transpiration and the top of the plant may dry out before the roots form.
Avoid planting too deep. The crown where the roots meet the plant should be just slightly below the soil line.
Moisture:
Moderate moisture until the plants are established. Plants may be allowed to dry down slighlty once finished.
Avoid overwatering.
Planting Level:
The crown (where the roots meet the plant) should be just slightly below the soil line.
PGRs/Pinching:
No pinching or PGRs are required.
Lighting:
Requires high light levels.
Grower Tips:
Helictotrichon is a cool season grass. Avoid planting during warmer months.
Pay attention to the planting depth and moisture control.
