Description

Corkscrew Rush, also known as Juncus effusus ‘Spiralis’, is a striking perennial grown for its wonderfully twisted, corkscrew-like green stems. Slim, cylindrical and leafless, the stems curl and tangle as the plant matures, forming a dense, architectural clump that never fails to attract attention. Reaching around 45–60cm tall, it can be planted in shallow water from 0–15cm deep or in permanently moist soil. Ideal for pond margins, bog gardens and wetland areas, this plant thrives in sun or partial shade and prefers moist, slightly acidic conditions. In summer, it produces small, subtle brown flowers, though its real appeal is the dramatic foliage, which looks great year-round thanks to its evergreen habit. Corkscrew Rush can also be used indoors. Easy to care for and full of character, it makes a unique houseplant and looks stunning as a standalone feature or mixed with leafy and flowering plants. The quirky curled stems are even popular with florists for adding texture to bouquets. Whether planted outdoors or displayed inside, this charming rush delivers personality, movement and lasting visual interest with minimal effort.

Planting Conditions

Ophiopogon, also known as Mondo Grass, thrives in partial to full shade, making it ideal for shaded garden areas. It prefers moist, well-drained soil rich in organic matter. To plant, dig a hole slightly larger than the root ball, place the plant at the same depth as it was in the pot, and backfill with soil. Space plants about 20-30 cm apart for ground cover. Mulching helps retain moisture and suppress weeds. Ophiopogon is versatile and can also be used in borders, rock gardens, or as edging.

Watering & Feeding

Ophiopogon, or Mondo Grass, requires regular watering, especially during dry periods and the first growing season to establish a strong root system. Water deeply to encourage deep roots but allow the soil to dry slightly between watering sessions. Once established, it is relatively drought-tolerant. We recommend you fertilise in Spring with a balanced slow-release fertiliser to promote healthy growth. Avoid over-fertilising, as this can lead to excessive leaf growth at the expense of flowers. A layer of mulch helps retain moisture and provides nutrients as it decomposes.

General Care

Ophiopogon 'Nigrescens', is low-maintenance and rarely requires pruning. Trim any damaged or dead leaves in early Spring to keep the plant looking tidy. If the plant becomes too dense, divide it every few years to promote healthy growth. Ophiopogon is generally pest and disease-resistant, making it an excellent choice for low-maintenance gardens. Occasionally, slugs or snails may target the leaves, but these can be controlled with organic or chemical treatments. Overall, it is a resilient plant with minimal issues.
