Juncus patens is a species of grass-like plant known by the common name Common Rush. It is native to the western United States from Washington to California, and its range may extend into Mexico. Within California it is found primarily along the coastal and coastal mountain, in marshes and other wet areas. However, it can also be tolerant of summer drought and garden conditions. It is a perennial herb forming narrow, erect bunches of stems arising from a central clump. The stems are thin, gray-green, often somewhat waxy, and grooved, and grow 30 to 90 centimeters in maximum height. The leaves have no blades; they appear as brown sheaths around the base of the stems. The flower cluster sprouts from the side of the stem rather than its tip. It holds many flowers, each of which has short, narrow, pointed petals and six stamens. The fruit is a spherical red or brown capsule which fills and bulges from the dried flower remnants when mature. It is popular in somewhat formal gardens, water gardens, and restoration projects. There are several available cultivars including ‘Carman’s Grey’, ‘Elk blue’ and ‘Occidental Blue’.

This plant is tough and easy to grow. It is happy in areas that are damp year-round, but also looks good and healthy in fairly dry soils with only minimal irrigation in summer.
