← Back to Plant Identification Guide | Product Cross-Reference | Ecoregion Guide
Identification
Rushes have stiff, round, solid stems (unlike the hollow stems of grasses or the triangular stems of sedges). They grow in dense clumps along pond margins and wet areas. Flowers are small, brownish, and clustered along the upper stem. Key distinguishing features:
- Stiff, round, solid stems ("rushes are round")
- Dense clumping growth habit
- Small brownish flower clusters on upper stem
- No true leaves in many species (stems are photosynthetic)
Commonly confused with: Sedges (triangular stems — "sedges have edges"), Bulrush (typically taller, different flower structure), Grasses (hollow, flat stems)
Treatment
Rushes are generally beneficial and rarely require treatment. Cutting or selective removal is preferred over herbicide.
- Glyphosate 5.4 — Foliar application to emergent growth.
- Cutting — Repeated cutting below the water line can reduce stands.
