Thingrass (Agrostis pallens) is a perennial grass that makes an eco-friendly lawn alternative, requiring half the water of non-native grasses. Its deep green color lasts year-round with weekly summer watering, and it tolerates light foot traffic.

Thingrass grows up to 2 feet tall but typically reaches about 1 foot in height and width. Its narrow leaves, usually under 2 inches long, complement its feathery flower clusters. Mowing is optional; without it, the grass has a meadow-like appearance.

Adaptable to various soils, it thrives in sun or part shade, making it an ideal ground cover for under trees. Thingrass also attracts butterflies and moths, adding both beauty and ecological value.
