ColorGrass® Twister Corkscrew Rush

Spiraling, corkscrew stems that twist and curl in every direction — the most architecturally interesting grass you can grow in a container or water garden.

ColorGrass® Twister (Juncus effusus 'Spiralis') is a corkscrew rush with a genuinely unusual growth habit: the stems spiral and curl in tight, irregular coils that create a dynamic, sculptural texture unlike any other ornamental grass. The bright green, leafless stems twist in every direction, catching light and creating movement even without a breeze. It thrives in consistently moist to wet conditions, making it ideal for water gardens, bog gardens, pond edges, and containers kept consistently moist. Compact and low-maintenance, it adds year-round architectural interest wherever it grows.

What I love about it

Twister is the plant that makes people stop and look twice. The corkscrew stems are genuinely unusual — not just slightly wavy, but tightly spiraled in a way that looks almost artificial. It's a conversation starter in any container arrangement, a striking accent at the edge of a water feature, and a beautiful textural contrast to broad-leaved plants. It thrives in the wet conditions that most ornamental grasses hate, making it the perfect choice for rain gardens, pond margins, and consistently moist spots where other grasses struggle. Low-maintenance, year-round interest, and completely unique.
