A species of sedge known by the common name San Diego sedge. It is native to the southwestern United States and far northern Mexico, where it grows in wet places, sometimes on serpentine soils. This sedge looks somewhat like a cattail. It produces angled stems easily exceeding a meter in height surrounded by leathery grey-green to reddish-green leaves (if drought stressed) up to about 1.2 meters long. The flower cluster is up to 80 centimeters long, with many long reddish brown flower spikes, each holding up to 300 developing fruits.
This is a easy and fast growing plant for full sun and heavy, moist soils. In even part shade, it tends to get weedy and unattractive. Needs plenty of water, so best to grow this in a sunny spot along a creek, seep or other naturally moist area, or in a regularly irrigated area.
