Orchardgrass (Dactylis glomerata)
Perennial grass
A clump-forming perennial often grown as a forage but also occurring as a weed of turf, landscapes and occasionally agronomic crops. Orchardgrass has a distinctive bluish green color that stands out from most other grass species. Leaves are 3 to 12 inches long, 3 to 8 mm wide, distinctly keeled, without auricles, and with a large (3 to 5 mm) membranous ligule. Leaf sheaths are strongly flattened or compressed compared with those of most other grass species. Seedheads are panicles ranging from 2 to 8 inches in length.
