Care & Growing Information
Site & Light: Plant in full sun for the strongest vertical habit and bluest color; tolerates partial shade in hot climates.
Soil & Water: Prefers moist to saturated soils; thrives in rain gardens, swales, and pond shoulders. Handles shallow standing water; avoid chronically dry sites.
Planting: Set crowns at or just above surrounding grade in wet ground. For containers, use a moisture-retentive mix and keep evenly saturated.
Maintenance:Low-care. Leave stems for winter structure, then cut back or comb out old growth in late winter/early spring. Minimal fertilizer—excess fertility can soften the habit.
Design Tips: Repeat in rhythmic vertical rows for contemporary schemes, or mass along stormwater paths for filtration and crisp geometry. Pairs well with moisture-loving sedges and irises.

The Juncus Inflexus Blue Arrow, commonly known as Blue Arrow Rush, is a distinctive ornamental grass prized for its striking upright, columnar form and steely blue-green foliage. This cultivar of Juncus Inflexus offers a unique architectural element to garden designs, providing vertical interest without spreading aggressively. Its compact growth habit makes it an excellent choice for smaller gardens, rockeries, or as a striking accent plant in mixed borders.
This rush species is well-suited for moist to wet conditions, thriving in areas such as pond edges, bog gardens, or rain gardens. Its slender, erect stems create a visual impact that remains appealing throughout the year, even in winter. The Blue Arrow Rush is a low-maintenance plant that adds texture and color, contributing to a more naturalistic and environmentally conscious landscape design.
Cultivating Juncus Inflexus Blue Arrow
To ensure optimal growth and appearance of your Juncus Inflexus Blue Arrow, it's important to provide it with the right conditions. This plant prefers full sun to partial shade and thrives in consistently moist to wet soil. While it tolerates a range of soil types, it performs best in loamy or sandy soils that retain moisture.
Regular watering is crucial, especially during dry periods, to maintain the lushness of its foliage. Minimal pruning is generally required; however, old or damaged stems can be removed in late winter or early spring before new growth emerges. This hardy rush is also known for its drought tolerance once established, though it will always perform best with consistent moisture.
