- Drooping sedge is commonly found in or near wetlands, riparian areasAreas that are directly adjacent to flowing streams, creeks, or rivers., ditches, and roadsides.
- It typically grows in full to partially shady environments and damp to wet soils.
- Drooping sedge spreads by seed. A single plant can produce as many as 20,000 seeds annually!
- Its ability to quickly spread allows it to easily outcompete native wetland species, creating a monocultureGrowing a single crop or plant..
What you can do about it:
- If you think you’ve found drooping sedge, please report it to the Oregon Invasive Species Hotline.
- Manual treatment of drooping sedge is not recommended for treating large infestations because it can re-sprout from fragmented rhizomes.
Drooping sedge is very similar in appearance to many other native sedges including slough sedge (Carex obnupta). Generally, slough sedge is smaller, with shorter flower spikes. Slough sedge’s leaves are also thinner than drooping sedge. It’s best to consult with a weed identification professional before trying to treat drooping sedge.
