About Beach Blue Grass (Poa confinis) Nurseries Show All Photos Poa confinis is a species of grass known by the common names coastline bluegrass and beach bluegrass. It is native to the coastline of western North America from British Columbia to northern California, where it grows on beaches, dunes, and other coastal habitat. Poa confinis is a perennial grass growing in small tufts with rhizomes and stolons, reaching up to about 30 centimeters tall.
