Iris 'Silver Edge': Refined Elegance with a Touch of Frost

Cool-toned and sophisticated, Iris 'Silver Edge' enchants with broad, lavender-blue falls delicately trimmed in silver-white. Tall and upright with soft ruffles and a luminous glow, this stately Siberian iris adds a crisp accent to late spring borders—graceful, refined, and easy to harmonize in a wide range of planting styles.

Plant Characteristics:

• Height: 75–90 cm
• Spread: 50–60 cm, forming upright, arching clumps
• Flower Colour: Lavender-blue with a fine silvery-white edge
• Flowering Period: Late spring to early summer
• Foliage: Narrow, sword-like green leaves with graceful arching form
• Sunlight Requirements: Full sun to light part shade
• Soil Requirements: Moist, well-drained soil; tolerates heavier soils with consistent moisture

Uses and Benefits: Iris 'Silver Edge' brings a touch of elegance to perennial borders, water-adjacent plantings, and meadow-style groupings. Its subtle colouring pairs beautifully with whites, blues, and soft yellows, while its vertical form contrasts well with broader leaves and frothy textures. Drought-tolerant once established, it also performs reliably in rain gardens and moisture-retentive areas.

Companion Plants: Pair Iris 'Silver Edge' with Deschampsia cespitosa, whose fine-textured green plumes echo the iris’s upright grace while thriving in the same moist, sun-tolerant conditions. Add Phlox 'Maybreeze' for a soft cloud of fragrant white blooms that overlap the iris’s season. Introduce Polemonium 'Heavenly Habit' as a compact accent with violet-blue flowers and greater sun tolerance than most Jacob’s ladders.

Care Instructions: Plant in full sun to part shade in moist, well-drained soil. Water regularly in dry periods. Cut back flower stalks after bloom, and remove declining foliage in fall. Divide every 3–4 years in spring to maintain vigour and control spread.

History: Iris 'Silver Edge' is a long-standing Siberian iris cultivar, selected for its soft colouring, garden reliability, and exceptional winter hardiness. Its cool-toned palette and strong constitution make it a versatile favourite in both formal and naturalistic designs.

Final Thoughts: Crisp, clean, and timeless, Iris 'Silver Edge' glides effortlessly into sunlit borders—bringing brightness, balance, and quiet grace to late spring compositions.
