A Stunning Grass
by Mooch, April 27, 2019

I want to advise that this is the prettiest grass that I have ever seen. It's not that tall and it has the blue/green color. We initially purchased this plant through the nursery and did very well for 1 yr, after putting down mulch I lost them all except for one little guy...I was devastated. After 2 yrs we were advised I could order them through Monrovia. When they arrived (promptly) I was concerned because each plant was sparse...but they have filled in nicely since March and keeping my fingers crossed I will have them for years to come.
