Fragile Sheath Sedge: A Western Native Worth Getting to Know
Meet the fragile sheath sedge (Carex fracta), a charming native perennial that might just be the unsung hero your western garden needs. While it may not have the flashiest name in the plant kingdom, this humble sedge brings authentic regional character and ecological value to landscapes across the American West.

Don’t let the fragile in its name fool you; this is a hardy native that has been thriving in western landscapes long before any of us started thinking about garden design. As a true native to the lower 48 states, it has deep roots in the ecosystems where it naturally occurs.
