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.
There are very few rules in gardening, but perhaps the most important one is to work within your zone. Choosing plants that grow and thrive in your particular climate is the very first step toward having a beautiful garden . Learn More
