Jointed Rush

Description

Jointed rush (Juncus articulatus) is a native perennial rush commonly found in wet and marshy habitats across the UK. It forms loose clumps of upright, green stems and thrives in consistently damp conditions, making it well-suited to wet meadows, lake margins, and shallow water. This adaptable species occurs from lowland plains to upland areas.

How to Identify

Jointed rush has slender, cylindrical, jointed stems with visible nodes along their length. The flowers form a tight, brown cluster that appears to grow from the side of the stem, typically about a fifth of the way down from the top rather than at the tip. Flowering usually takes place in summer, with the small, brown flowers being wind-pollinated.

Where It Grows

This species grows in marshes, wet meadows, small streams, and along the shores of lakes and ponds. It tolerates shallow standing water as well as waterlogged soils and is found across a wide range of habitats, from lowland wetlands to mountainous regions.
