Wiry foliage corkscrews outwards and upwards from the crowns of the Thread Rush (Juncus filiformis Spiralis). This has to be one of the most interesting of the rushes thanks to the crazy foliage. It's gorgeous in pots, but it is at is best in the water garden, either as a marginal plant or partially submerged in water. This whimsical plant is the perfect choice for lovers of the unusual, and its high water requirement can work to your advantage if you use it cleverly. The flowers are relatively insignificant, but who cares? With leaves like these, nothing more is needed to add to its charm.
