Follow-up to “Rye or Not?”

Notes:

Here are three pics of the long-stemmed grass that I thought was rye when I overseeded in the fall. The bag for sure was labeled “rye” but this is so different than when I’ve over-seeded my bermuda in past years. These samples were in mulch directly next to the front yard so I’m certain this is the same variety but with seed-heads.

Thank you in advance for your time and diagnosis of this plant. And if it IS fescue, will it burn out in the summer or do I need a post-emergence herbicide?

    These could still be a type of ‘rye’. The confusion is probably from of the use of common names for plants are in the same family i.e. Poaceae/Gramineae. I’m not an expert of this genus and used these helpful links to narrowing down some of the grass plants with their vegetative ID.

    You had mention it grows real fast, also your previous post show the ‘auricle’ on one of the stem/culm. To my eyes it looks similar to the annual ryegrass/ Italian ryegrass perhaps (Festuca perennis syn. Lolium multiflorum)? Again I’m only speculating. Best wishes!

    Great link for identify grass plants. All three types are from slide number 39 through 51.

    I want to add that Schedonorus phoenix is syn. of Festuca arundinacea (tall fescue).
