Blue Flag Iris ‘Purple Flame’

Blue Flag Iris ‘Purple Flame’ adds a vivid burst of spring drama to moist gardens, rain gardens, or streamside plantings. Its standout feature is the early-season flush of deep burgundy to purple basal foliage, which emerges weeks ahead of bloom and gradually fades to green as the season progresses. By late spring to early summer, the plant produces elegant violet-blue blooms that attract bumble bees, hummingbirds, and other native pollinators.

Like the straight species (Iris versicolor), ‘Purple Flame’ thrives in moist to wet soils and performs beautifully along pond edges, in wet meadows, or anywhere consistent moisture is available. It spreads slowly by rhizomes to form striking clumps 2–3 feet tall, pairing beautifully with sedges, rushes, and other wetland plants. This iris also serves as a host plant for native butterflies and moths, and its clumping growth helps stabilize soil in restoration and ornamental settings.

Special Note: Blue Flag Iris ‘Purple Flame’ is a garden-selected variant of native Iris versicolor and retains the species’ core ecological value. It was chosen for its spring foliage color, not at the expense of nectar production or habitat function. For gardeners seeking both aesthetic appeal and wildlife support, this is a trustworthy native-adjacent option.

Why Choose Blue Flag Iris 'Purple Flame'?

• Early spring purple foliage adds dramatic color contrast.
• Thrives in rain gardens, wet meadows, and pond edges.
• Supports native pollinators and serves as a host plant.
• Tolerates occasional dry spells once established.
• Spreads slowly to form bold clumps in moist soils.
  

Cut back spent flower stalks if desired, and divide clumps every 3–4 years in early spring or fall to maintain vigor. Plant in moist soil or shallow standing water for best results. Remove older foliage in late winter to allow new growth to shine.

• Water: Prefers consistent moisture—ideal for wet soils, but can tolerate short dry periods once mature.
• Soil: Grows best in rich, organic, slightly acidic soils; tolerates clay and shallow water.
• Sunlight: Full sun to part shade; more blooms in full sun, lusher foliage in light shade.
• Division: Divide every 3–4 years in early fall or spring to maintain vigor and prevent overcrowding.
• Pruning: Remove dead leaves and spent bloom stalks in late summer or early fall.
• Deer resistance: Generally unpalatable to deer and rabbits.
