Through the years I've tried just about everyone for bulbs but A.D.R. is tops. It's a family run business and the service levels and expertise are as good as the product they sell. My clients rave about the results we get with A.D.R. and that makes me happy.

Iris Germanica 'Five O'Clock'

Bearded Iris

Bearded Iris ‘Five O’Clock’ is a tall bearded iris, reaching 32 inches in height. It features rosy‑lavender standards and deep plum‑purple falls edged with a soft, lighter halo. The gold‑and‑violet beards add a glowing contrast, giving the blooms a rich, dimensional look. A mid‑season bloomer, it brings bold, saturated color to the garden at a time when many varieties are finishing their first flush.

Thriving in full sun to part shade, ‘Five O’Clock’ prefers well‑drained, humus‑rich soil and is deer‑resistant. Though it is not a rebloomer, its vigorous growth and dramatic coloration make it a standout choice for borders, mixed perennial beds, and collectors seeking strong visual impact in the heart of iris season.

Growing and Maintenance Tips for Iris Germanica 'Five O'Clock'

Planting: Plant rhizomes in late summer to early fall or early spring. Set them horizontally with the top of the rhizome just at or slightly above soil level. Space 12 to 24 inches apart for good air circulation.
Location: Full sun is ideal (6+ hours daily). In hot climates, light afternoon shade helps prevent leaf scorch.
Soil: Well-drained, moderately fertile soil with a neutral to slightly acidic pH (6.0–7.0). Avoid heavy or soggy soils—add grit or compost to improve drainage.
Watering: Water after planting and during dry spells. Once established, bearded irises are drought-tolerant and prefer drier conditions.
Temperature: Hardy in USDA zones 3–9. Tolerates cold winters and summer heat.
Fertilization: Apply a low-nitrogen fertilizer (e.g., 5-10-10) in early spring and again after blooming. Avoid overfeeding.
Pruning: Remove spent flower stalks and yellowing leaves. Cut foliage to 6 inches in late fall to reduce overwintering pests.
Propagation: Divide rhizomes every 3 to 4 years in late summer to maintain vigor and prevent overcrowding.
Pest & Disease: Watch for iris borers, soft rot, and leaf spot. Good drainage and air circulation help prevent issues.
