Some blue, some green

Hoping once these get planted they are all the same color. Kind of vary between green, blue and tan. I’ve purchased Elijah blue fescue at big box stores and these look much healthier.


Blue dune Lyme grass

The plants were packaged well but a lot of the grass is brown and looks soggy and week with easy breakage.. they will come in with new growth, but for now they look horrible in the ground.

My Review

Overall the plants and the shipping experience was pretty good, but I was a little disappointed on how "root bound" in the container the plants were. This gives the impression they have been "sitting around" for a while. The dense roots didn't even allow me to work the root ball with my fingers per your instruction sheet.
