Corkscrew Rush is a spiraling variant of soft rush that transforms wet spaces into living sculpture. This rhizomatous perennial grows 12 to 24 inches tall in dense clumps, its distinctive twisted green stems creating architectural interest from spring through fall. Hardy in zones 4 through 9, it thrives in full sun and tolerates standing water up to 4 inches deep, making it equally at home in rain gardens, water features, or consistently moist garden beds. Rust, leaf spot, and stem rot may occasionally appear, but serious pest problems are rare. Low maintenance and evergreen in warm climates, it spreads slowly by rhizomes and self-seeding, giving you years of sculptural presence with minimal fuss.

The spiraling stems set Corkscrew Rush apart from its straight-stemmed relatives, creating an ornamental effect that holds interest even when flowers fade. This plant handles both standing water and regular garden soil equally well as long as moisture stays consistent. Full sun brings out the richest color in the stems, and the foliage remains evergreen in mild winters, offering garden structure year-round. It thrives in zones 4 through 9 with virtually no maintenance, spreading gradually through rhizomes that can be contained by growing it in sunken containers if needed. The low horizontal spread of 12 to 18 inches makes it compact enough for smaller water gardens while the twisted form catches light in ways traditional straight-stemmed rushes never could.
Corkscrew Rush shines in rain gardens where it helps stabilize wet edges and adds visual interest during seasonal standing water. It works well around pond margins and in shallow water features, where its twisted stems become sculptural focal points. In regular garden beds kept consistently moist, it provides year-round texture and structure. The spreading rhizomatous growth helps control erosion on wet slopes and clay banks, making it valuable for soil stabilization in landscape situations.
