Spacing & Landscape Use Spacing Recommendations Space 18 - 24 in apart for massing in wet conditions or naturalized areas. Landscape Placement Best suited for rain gardens, swales, wetland restorations, and pond edges where water retention is high. Adds vertical contrast to moist or aquatic plantings. Companion Plants Carex stricta (Tussock Sedge) - Complements with clumping habit and similar water needs. Lobelia cardinalis (Cardinal Flower) - Adds red summer blooms and supports hummingbirds in wet soils. Iris versicolor (Blue Flag Iris) - Provides showy flowers and thrives in moist conditions alongside Juncus. Caltha palustris (Marsh Marigold) - Offers early yellow blooms in wet meadows and bogs. Sagittaria latifolia (Duck Potato) - Adds architectural foliage and supports aquatic pollinators.
