Carex subfusca (Rusty Sedge) - Native sedge that has a wide distribution throughout the western US from the sea to the desert - generally found in seasonally wet meadows and creek beds. It has a narrow vertically-held dark green leaves to 8-12 inches tall and spreads by rhizomes to form dense stands. It is recommended for full sun with regular to occasional irrigation but we have found it very tolerant of shade and considerable drought in our own planting at the nursery. Hardy to USDA Zone 5 ( -20° to -10°F). A great meadow component. Control spread with barriers or irrigation practices. As with many of the Carex there is some confusion about this name. Plants described as C. teneraeformis are currently now considered to be C. subfusca as well. Our plants come from the Santa Barbara Botanic Garden Plant Introduction Program.
The information about Carex subfusca that is displayed on this web page is based on research conducted in our nursery's horticultural library and from reliable online resources. We will also include observations made about this plant as it grows in our nursery gardens and other gardens that we have visited, as well how the crops have performed in containers in our nursery field. We also incorporate comments that we receive from others and welcome hearing from anyone with additional information, particularly if they share cultural information that aids others growing this plant.
Please note that after 46 years in business, San Marcos Growers will be discontinuing nursery operations by the end of 2025 and the property will be developed for affordable housing.
