Special Attributes

Blue Arrows Rush is an evergreen perennial grass prized for its thin blue leaves and the soothing color and fine texture it provides in garden beds or containers. The stiff, thin leaves emerge lime green in color turning blue and remaining that color throughout the rest of the year, even during winter. Though this one is often grown as a bog or pond plant it is also drought tolerant in garden beds. Juncus are tough, versatile, and evergreen in most climates, and Blue Arrows won't disappoint.

Landscape & Garden Uses

Growing in an upright clump 24 to 36 tall and 12 to 18 inches wide, Blue Arrows Rush is ideal for use as an accent or in groupings or mass plantings in landscape borders, garden beds and home foundation plantings. Excellent for use in pots, planters and other containers which can be placed on the patio or in the margins of the garden pond. A fine addition to ornamental grass gardens, bog gardens, rock gardens, and blue color theme gardens.

Cultural Preferences

Blue Arrows Rush is easy to grow in moist any wet to dry soil of average fertility in full sun to part shade. Grows well in standing water so is suitable for use in the garden pond with the base of the plant at water level or higher. Maintenance is minimal. If necessary, the foliage can be refreshed annually, before new growth begins to emerge in spring, by cutting back the old stems. After doing so, bright, new greenery will emerge in spring. This duplicates what happens naturally in its northern most range, where the frost kills its greenery back to ground level.
