the flat straw grass

[Anglicist]

I don't understand how we can translate it because I found that "straw" and "grass" are two nouns. Can I say "la pelouse de paille plate" ?

Merci de m'aider.

I have googled "straw grass", and it appears to me that it is a species of grass. However, I've been unable to find any information on what it is called in French.

Thank you Seneca ! I think that I will translate it thanks to "herbe folle".
