JUNCUS PATENS
Common names are spreading rush and California gray rush.
Native to the West Coast of the United States from Washington to California, and into Baja Mexico, it grows at seeps, springs, and streambanks in stream beds and on river and pond banks, in marshes, and in other moist habitats.
Juncus patens is cultivated as an ornamental plant, for use in traditional and wildlife gardens, and in natural landscaping design, and in habitat restoration projects. Its tall narrow form fits into narrow garden beds and planters adjacent to walkway walls, and in container planting. Despite its moist habitat origins, it can be very drought-tolerant when established.
