Calamagrostis canadensis (Bluejoint Grass)

A key structural species for wet prairie and sedge meadow restoration, bluejoint grass combines strong streambank-stabilizing rhizomes with a documented high deer resistance rating - a rare combination for a wetland grass this productive.

Species Overview

Calamagrostis canadensis, commonly known as Bluejoint Grass, is a native cool-season grass that forms dense clumps and thrives in wetland habitats. It grows up to 4 to 5 feet tall, with narrow, upright leaves and airy flower panicles that turn golden as they mature. Its adaptability and attractive form make it a popular choice for naturalized plantings and wetland restoration projects.

Application

• Wet meadow, marsh, and riparian zone restoration
