Poa douglasii is a species of grass known by the common names Douglas' bluegrass and sand dune bluegrass. It is endemic to the coastline of California , where it grows in shifting sand dunes. It can be found mostly along the Central Coast and Channel Islands, and occasionally on the North Coast north of Mendocino. It is a perennial grass growing small, dense clumps up to about 30 centimeters in maximum height. It grows from a network of long rhizomes and stolons that anchor the grass to its loose sandy substrate; this network may be up to one meter long.[1] The inflorescence is a dense, oval-shaped series of overlapping spikelets. The grass is dioecious, with male and female individuals producing different types of flowers in their inflorescences.[2] This species, like many sand-dune endemic plants, is threatened by invasive species.
