Thank you for your grass identification question. Grasses can be difficult to identify from a photo. Following is a link to an OSU Extension publication entitled, “Guide to Common Grasses in Central Oregon”. This resource may be helpful in identifying the type of grass in question.
I recommend that you call the OSU Master Gardener Plant Clinic. The Master Gardener on duty can talk with you about the plant and do research to provide a more definitive identification. You may be asked to provide additional photos or bring part of the plant to the OSU Extension Office to assist with identification.
You can call and talk with the Master Gardener on duty by calling 541-548-6088. You can also submit questions with photos to the Master Gardener Plant Clinic email: firstname.lastname@example.org. We always welcome your home garden questions.
