Yes, this is a grass. It's called Schizachyrium scoparium, also known as Little Bluestem and not only is it a native plant, but it is a great pollinator plant!
It's a favorite for Dusted Skippers and a handful of others, as well as insects such as grasshoppers and beetles. Songbirds also make use of the seedheads that form each fall. It's great for wildlife.
While this warm season grass with its silver blue coloring looks beautiful in the heat of summer (it tolerates drought well), the oranges hues make a really pretty sight in the fall.
In case you wondered, it is deer resistant and pests do not seem to bother it.
We are happy to highlight it in our Pollinator Pathway garden and share the benefits of it with you.
