Can be planted in 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.

This sedge has a wide distribution throughout the western North America from Washington south to Baja California from the sea to the desert. It is also listed as native to the Hawaiian Islands and surmised that it came there by being deposited by birds. It is generally found in seasonally wet meadows and creek beds. The name for the genus is a Latin word describing the sedges and the specific epithet combines the prefix 'sub' which means "somewhat" or "slightly" with fuscus meaning "brown," "dark," or "dusky" in reference to the rusty foliage and brown flowers.

As with many of the Carex there is some confusion about this name. Plants described as Carex teneraeformis are currently now considered to be C. subfusca as well. Our plants come from the Santa Barbara Botanic Garden Plant Introduction Program. We grew this plant from 1999 until closing the nursery in 2025. 

The information displayed on this page about Carex subfusca is based on our research conducted about this plant from books in our nursery library as well as from information that is provided by reliable online resources. We also have included our own observations made about it as it grew in the nursery gardens and other gardens visited, as well how the crops of this plant performed in the containers when we had them in our nursery field. We also include comments received from others and welcome hearing from anyone who has information about this plant, particularly if it includes cultural information aiding others to better grow it.
