Hello Tonja

Ornamental Spider Grass: One of a host of common names for ornamental clumping perennials belonging to the botanical genus Liriope, spider grass is also commonly called monkey grass, border grass, Aztec grass, lilyturf, and liriope. A popular ground cover or edging plant, liriope with longer, arching grass-like leaves are often dubbed spider grass, especially in the Midwest. Two species of liriope are grown in gardens: Liriope muscari and Liriope spicata, best across U.S. Department of Agriculture hardiness zones 6 through 10.

Not invasive!!

Liriope is a sturdy ground cover that is great to replace turf on a steep bank. See the picture at this link: https://www.canr.msu.edu/news/smart_gardeners_replace_worn_out_turf_with_thrifty_ground_covers
