I recently planted tall fescue in the shaded, wet areas of my lawn (mostly around the patio) as the couch grass simply would not grow there. I noticed there was a fine, long, dark green clump grass starting to grow in this area as I was throwing the tall fescue seed down. It has since grown into lush, dark green ground cover that blends in perfectly with my blue couch lawn. It grew fast too.
I need to find out what this is and replace the tall fescue I laid down with this! I'm going to take a guess and say it's Bluegrass or Buffalo Grass.
