Corkscrew Rush Spiralis

Availability: Out of stock

Are you looking to add a little playful whimsy to your garden? The Corkscrew Rush plant (Juncus effusus f. spiralis) will add loads of it! This striking plant never fails to get double-takes, compliments, and comments! Not having typical leaves like other plants, Rush Grass leaves have cylindrical smooth foliage like nothing else you've seen!

Growing into upright clumps, 10-12 inches tall but spreading 12-18 inches wide, Corkscrew Rushadds a completely new dimension of texture to your landscape. Occasionally the spiraling foliage is accented by unusual tufts of white flowers that become extra whimsical spikey round seedpods along tall slender stems during the summer!

Being a member of the Rush family (remember Rushes are round) you know that Corkscrew Rush plant care is going to be easy! Hardy throughout a wide range of USDA planting hardiness zones from 5 to 11, these little moisture-loving plants are sure to please!

Planting and Application:

Looking like Grass having a bad hair day (or maybe a really good one!), Corkscrew Rush's twisty, curly, springy foliage provides standout texture around your water features, ponds, and Rain Gardens! Even doing fantastically in a barrel rain garden with a little bubbling fountain! Big or small, your water garden ecosystem will benefit from these unique perennial plants!

Combine Spiralis Rush with wider-leaved water garden plants like Flag Iris, or for a lush, wild look among equally whimsical Papyrus plants! For a truly eye-popping juxtaposition try planting it with ram-rod straight Soft Rush Grass or fine and flowy Bottlebrush Sedge Grass. Mix and match with larger Corkscrew Grasses like Big Twister!

Thriving in marshes, swamps, and other soggy areas in nature, Rush Grasses like Corkscrew can spread by rhizomes and will even remain evergreen in mild winter climates. In-ground or in containers, you'll love these quirky little plants!

#ProPlantTips for Care

Corkscrew Rush likes full sun or partial shade and lots, and lots of water. It can even thrive in standing water at the edge of a pond so long as it isn't stagnant. Provide regular moisture access for plants located in average garden soils. In cooler climes, the foliage becomes yellow, then brown in fall to winter dying back to the ground like a perennial. In warm climates, it can be semi-to-fully evergreen. Either way, clean and prune the mounds in the very early spring for best results.

  • Full Sun & Part Shade
  • Moist Soil & Tolerates Average Soil Moisture
  • Well-Drained Environments
  • Prune Back Early Spring
  • Rarely Damaged By Deer

The fun and quirky Corkscrew Rush Grass will provide a truly unique look for your garden, but only if you order yours today at Nature Hills Nursery!
