Big Twister Rush

Juncus effusus 'Big Twister'

Large, spiraling foliage, resembling giant corkscrews twisting and turning, creates a dramatic effect over water. A great deer-resistant accent plant that collectors dare not do without. Clumps slowly broaden by creeping rhizomes. This low maintenance plant is ideally sited in a bog or other very moist, bright shade location. Adapts well to containers.
