Spiny Rush
Juncus Acutus
Overview
Spiny Rush (Juncus acutus) is a robust, evergreen perennial with an upright, clumping growth habit reaching 2-3 feet tall and wide. Notable for its pointed, spiny-tipped green stems, this rush thrives in full sun to part shade and prefers moist to wet soils, tolerating brackish conditions. It's excellent for natural water features, providing habitat for wildlife and erosion control with minimal maintenance. Care should be taken due to its sharp foliage.
