Harford’s Sedge: A California Native Perfect for Wet Spots
If you’ve been scratching your head about what to plant in those soggy areas of your California garden, let me introduce you to a real problem-solver: Harford’s sedge (Carex harfordii). This unassuming native sedge might not win any flashy flower contests, but it’s absolutely brilliant at what it does best – thriving in wet conditions while supporting local ecosystems.
What Makes Harford’s Sedge Special?
Harford’s sedge is a true California native, found exclusively in the Golden State. This perennial sedge belongs to the grass-like family of plants, though it’s technically not a grass at all – it’s a sedge! You can tell the difference by remembering the old botanist’s rhyme: sedges have edges (referring to their triangular stems).
Also known by its botanical name Carex harfordii, this plant was historically classified as Carex montereyensis, so don’t be confused if you see that name floating around in older gardening references.
Where Does It Call Home?
This sedge is endemic to California, making it a fantastic choice for gardeners wanting to support truly local ecosystems. You’ll find it naturally occurring throughout the state, from coastal regions to inland foothills.
