effusus (soft rush) has been identified as one of the most important species causing problems through competition. Juncus spp. were the most frequent vegetation type found on the cutaway bogs during the survey, while J. effusus was the plant most frequently found on the cutaways during the vegetation survey (Parr ) (Figure 1.

Care for Juncus Spiralis. Juncus effusus Spiralis, also called Corkscrew Rush, is a low maintenance grass-like perennial that grows to a height of about 18 inches, producing stems with a corkscrew.

The cultivar Juncus effusus 'Spiralis' (syn. Juncus spiralis), with the common names corkscrew rush or spiral rush, is a distinctive potted and water garden plant due to its very curled spiral like foliage.
