Juncus effusus

Juncus effusus 'Spiralis' is an aquatic perennial with a rootstock. It forms clumps of upright or sprawling corkscrew-like stems and has semi-evergreen dark green glossy smooth foliage.

Reaching a medium height of 40 to 50 cm (16 to 20in), the spiral rush produces loose brownish-red spikelets in the heart of summer. It thrives in heavy, moist, marshy soil and is essential at the edges of water features, where it adds a unique touch and an unmatched architectural effect.

It belongs to the family Juncaceae, Juncus effusus, a variety native to Europe, Turkey, the Caucasus, Iran, and Central Asia. It can be found in all temperate regions of the world.

In the wild, rushes grow along wet ditches and are closely associated with shallow, natural, stagnant waters. This rush is suitable for coastal use. It can be used to stabilise banks or, more decoratively, in a water feature or a container on the patio.
