Yellow Nut Sedge

Cyperus esculentus


Appears to be a type of grass. Narrow blades. Burr-like seed head formations. Size of full plant unknown.


This sample was brought to me in hopes that you here at Noah could help identify it and whether it should be of concern. The plant was noticed recently in fields on the property and has since spread rapidly (within the last two years).

Exactly what we needed to know. Thank you.

This has been growing in my garden fairly aggressively as well. I hadn't posted it yet in hopes of getting an ID beforehand.

Check out the pictures on the links. Should be round, bulb like roots just under the ground. Tends to like wet areas Also are more yellow than the surrounding bluegrasses, fescues and ryes. Try the recommended weed treatment. If this is not too effective and the areas are small enough they can be hand pulled, especially if the ground is moist. If you pull them, be sure to get the bulb.
