Scouler's surfgrass is a marine flowering plant that forms dense clumps or beds on rocks in the intertidal zone, exposed at low tide and submerged at high tide. It is a seagrass, not a plant suited to home gardens, so care is mainly about its natural coastal conditions.

About
Phyllospadix scouleri, or Scouler's surfgrass, is a flowering marine plant in the family Zosteraceae. It is native to the coastline of western North America from the Alaskan panhandle to Baja California.
This slender, vivid green plant has long, flat blades. It grows in large clumps or beds exposed during low tide and submerged at high tide. It is found attached to rocks in the middle to low intertidal zones.
Where it grows
It is endemic to Baja California. It lives in rocky areas with turbulent tides.
Uses
Sea grass was used by Native American tribes along the Southern California Coast to make cordage and other woven objects, including specimens from San Miguel Island dated between about 10,000 and 8,600 years ago (see Connolly, Erlandson, and Norris 1992).
