Iris reticulata 'Harmony'
Dwarf Iris
Iris reticulata 'Harmony' is a dwarf iris, reaching 4 to 5 inches in height. It features royal blue flowers with a white-rimmed gold crest on each fall. The slender, grass-like gray-green leaves elongate to 15 inches after bloom before disappearing in late spring as the plant goes dormant.
This iris thrives in full sun to part shade and prefers well-drained soil with neutral to slightly alkaline pH. It is deer-resistant, drought-tolerant, and fragrant, making it a lovely addition to rock gardens, containers, and border fronts.

Growing and Maintenance Tips for Iris reticulata 'Harmony'
Planting: Plant bulbs in fall, 3 to 4 inches deep and 3 inches apart, with the pointed end up. For naturalized drifts, scatter and plant where they fall.
Location: Full sun to partial shade. Ideal for rock gardens, borders, and containers where early blooms can be appreciated up close.
Soil: Well-drained, sandy or loamy soil with a slightly acidic to neutral pH (6.0–7.0). Avoid heavy or soggy soils—add grit if needed.
Watering: Water after planting and during active growth in late winter and early spring. Once foliage yellows, reduce watering—bulbs prefer dry summer dormancy.
Temperature: Hardy in USDA zones 5–9. Requires 10–14 weeks of cold to bloom reliably.
Fertilization: Apply compost or a low-nitrogen fertilizer in early spring as shoots emerge.
Pruning: Allow foliage to die back naturally to feed the bulb. Remove spent flower stalks for tidiness.
Propagation: Naturalizes by offsets. Divide clumps in summer when dormant if needed.
Pest & Disease: Generally pest-free. Good drainage prevents bulb rot.
