Juncus Effusus ‘Spiralis’

Botanical Name: Juncus effusus ‘Spiralis’

Corkscrew rush (sometimes called Juncus spiralis) is a novelty cultivar with captivating coiled stems, spreading out in every direction as they grow.

If you like unusual indoor plants, you’ll want to add this spectacular ornamental to your collection. Stunning on its own, corkscrew rush also adds some sizzle among a display of leafy and flowering plants. In fact, those curly-Q stems are sometimes used in florists’ bouquets.

Perennial and evergreen, this is an easy-care house plant. It adds a lot of personality to a room for little effort.

Green Thumb Tip

Constantly wet soil is needed to keep Juncus effusus ‘Spiralis’ healthy and thriving.

Water generously. Don’t allow the soil to dry out. Foliage will turn yellow then brown if it gets too dry. It’s a good idea to keep your corkscrew rush plant in a pot without a drainage hole. Juncus is native to marsh areas, so it loves soggy soil — even standing water.

Shed some light. Put your Juncus plant in your sunniest window — or shift it outdoors for the spring and summer. It will tolerate lower light levels, but won’t grow much. If you don’t have a spot near a window, grow lights work beautifully.

Repot in spring, moving up to a container 1 size larger when it becomes crowded. Juncus is fast-growing when it gets the sunlight and water it wants. You may need to divide it every spring.

Help! My Juncus Spiralis Corkscrew Rush is dying!

Hi, I’m a total newb with house plants. I bought a “Unicorn Plant” from Ikea 2 weeks ago. Its in a plastic pot, it goes under the name “Juncus Spiralis”, and by my research, is also called a “corkscrew rush”. In the store it was beautiful and dark green, now its on its last legs. The sticker on the pot says:

“Bright, no direct sunlight (not sure what that means where I should put it exactly). Water thoroughly, allow potting soil to dry bewtween water. Mist leaves if air is dry. Fertilize every 2 months. Do not fertilize during winter”.

I dont have any fertilizer, and wouldnt know what to get, so I did not fertilize. I left it on a shelf about 10′ from the window. It was starting to turn brown, so I did some research on this plant, and read that it was a grass, that was supposed to love water and sun. So I soaked it plenty with water, left it sitting in the water, misted the leaves plenty, and put it outside for a day to try to revive it. That made it much, much, much worse. Now the stems are all dry, papery and crisp, wilted, ranging from light dull green to yellowish. It’s a mess! I brought it indoors and put it in front of the window, ‘cos I read somewhere it likes “full sun”. I don’t know anymore what it likes! But how could it have done so well in Ikea’s store with no windows, and done so poorly in my apt? Right now, the soil is moist, but its no longer sitting in water, I’ve drained that.

Can I save it if I cut all the stems? Will they regrow? This was a beautiful plant, I’d hate to see it go!

Care Of Corkscrew Rush: Tips For Growing Corkscrew Rush Plants

The corkscrew rush is a very versatile plant. It thrives equally well in well-drained soil or slightly boggy or marsh areas. Perennial corkscrew rush makes an excellent plant for use near a water feature, in container gardens or even as an indoor specimen. The other name for corkscrew rush, Juncus effuses “Spiralis”, refers to the spiral habit of this grass-like plant. Try growing corkscrew rush anywhere that plentiful water is available.

Corkscrew Rush-Juncus Effuses Info

This is one of those plants that just makes you smile, with the unruly foliage that springs unbridled from a cluster of stems. Corkscrew rush is a cultivar of a plant native to Japan. This horticultural hybrid was bred for the whimsical foliage. The round blades twist gently from the base all the way up to the top of the foliage. Deep green leaves often bear some striping, providing showy plants for partially shady areas.

You can grow corkscrew rush plants in USDA plant hardiness zones 4 to 9. The only limitation when growing corkscrew rush is very dry or arid conditions.

Growing Corkscrew Rush

Corkscrew rush plants produce best in full sun, except in zones with unrelenting heat. In the hotter areas, they will do just fine in a partially shady area or where there is shelter from midday sun.

Perennial corkscrew rush thrives in any type of soil including sand, loam or even mixed clay. Extremely dry areas are not suitable for the plant unless you provide superior irrigation and ensure the soil doesn’t dry out.

Corkscrew rush plants are not susceptible to many pests or disease and are very tolerant to most climates. Care of corkscrew rush should include maintenance pruning for appearance, watering and annual fertilizing.

Care of Corkscrew Rush

The perennial corkscrew rush is semi-evergreen. In the higher zones it will remain green throughout winter, but colder areas see the foliage turning brown. You can cut the foliage back when this occurs in very early spring to make way for new leaves.

Fertilize in early spring with an all-purpose water soluble fertilizer.

Watch for pests and disease and combat with appropriate solutions. Avoid fungal problems on the leaves by providing water under the leaves.

Indoor plants will need to be repotted every two or three years. Use a potting soil with plenty of compost and peat mixed into the basic blend. Keep container plants very moist and never let them dry out.

Uses for Corkscrew Rush Plant

Place the rush in groups along the edge of a pond or water feature. You can also partially submerge them in shallow or boggy areas.

Pot up a corkscrew rush with other water lovers, such as Japanese iris, cattails, dwarf papyrus or yellow flag. Use corkscrew rush in partially shady areas as fun borders.

Your imagination and too much dryness are all that keep you from using this amazing plant in many different ways.

Houseplants: 6 Gorgeous Growers

Earth Star (Cryptanthus)

  • Why we love it:Leaves have striking zigzag patterns, and the plant is pretty indestructible –unless you forget to water it. Aim for consistently moist soil.
  • Good to know:Leave edges often have sharp-looking teeth, but the texture is actually soft and harmless.
  • Secret to success:Light develops leaf color. Too much light, and leaves bleach, turning white. Too little, and color fades. Aim for a few hours of bright indirect light –on a table near a bright window.

Corkscrew Rush (Juncus effusus spiralis ‘Curly Wurly’)

  • Why we love it:The name is enough –Curly Wurly –but the quirky, corkscrew leaves are just plain fun.
  • Good to know:In the wild, Corkscrew Rush grows in marshes or bogs where there’s standing water.
  • Secret to success:Replicate soggy conditions by planting this curly character in a pot with no drainage holes. Or use a pot with drainage holes but slip it into another container without holes, and keep it filled with an inch or two of water. Bright indirect light is ideal.

Lady Palm (Rhapis excelsa)

  • Why we love it:This Palm is easy to grow and does so slowly, which means it won’t quickly outgrow a pot or room (like many palms). It’s exceptionally long-lived; keep it healthy, and you’ll need to bequeath it to a fellow plant lover.
  • Good to know:Brown leaf tips signal exposure to high temperatures, overwatering, low humidity, or fluoride. Use distilled or rain water to keep fluoride out of your plant’s diet.
  • Secret to success:Let soil dry out between waterings. Give plants low to bright indirect light –they’re not fussy.

Stromanthe Sanguinea ‘Tricolor’

  • Why we love it:Exotically colored leaves make this plant a looker. Each leaf has shades of pink, cream and green.
  • Good to know:Plants adapt easily to hydroculture –growing in a container filled with water and clay pellets.
  • Secret to success:High humidity is a must or else leaf tips turn brown. Learn ways to increase humidity. Bright indirect light fosters best leaf color.

Jungle Drum or Peruvian Fan (Carludovica’Jungle Drum’)

  • Why we love it:Pleated, seersucker leaves divided into twin lobes are real conversation starters.
  • Good to know:This is an understory plant in tropical forests. It withstands low light (placed where other plants usually fail), but does best with bright indirect light. Avoid full sun, which bleaches leaves.
  • Secret to success:Allow soil to dry about an inch deep before watering. Overwater, and lower leaves will quickly yellow and die. Underwater and you’ll get similar results –just more slowly.

Blue Chalksticks (Senecio serpens)

  • Why we love it:Thick, fleshy, blue-toned leaves extend up from soil like fingers. Plus, it’s a low-maintenance succulent.
  • Good to know:In frost-free regions, this blue beauty thrives in outdoor gardens as a ground cover. Give it a shallow pot indoors. Water when soil is dry. Provide bright light.
  • Secret to success:Succulents need sharply draining soil. Try a bagged cacti soil mix, but if the bag is light, it probably contains wood particles, which spell trouble for succulents. Instead, mix your own soil by blending equal parts regular potting soil with sharp sand.
