Description
Iris ensata 'Imperial Burgundy' is a striking spectacle for any water-loving border or pond edge, commanding attention with its rich, burgundy petals edged in a delicate, hairline white rim. The sharply defined yellow-white signal at the centre of each bloom contrasts beautifully against the deep burgundy style arms, giving Iris 'Imperial Burgundy' an air of refined drama that seems almost regal. Its elegant, ruffled petals unfurl gracefully in late spring to early summer, creating a waterfall of colour that pairs wonderfully with other Japanese water irises or soft, leafy foliage for a serene, contemplative display.
Beyond its rich tones, Iris ensata 'Imperial Burgundy' thrives in moist, well-draining soil, making it perfect for pond margins, bog gardens, or any sun-drenched, damp spots in your UK garden. Each flowering stalk of Iris 'Imperial Burgundy' lifts the blooms with poise, ensuring they remain prominent above surrounding foliage while attracting pollinators to your waterside planting. Hardy, adaptable, and undeniably showy, Iris ensata 'Imperial Burgundy' adds a sophisticated splash of colour and texture, turning an ordinary border into a jewel-like scene. With its dramatic burgundy petals, subtle white edging, and golden signals, Iris 'Imperial Burgundy' is a must-have for gardeners seeking elegance, contrast, and a touch of theatrical flair in any late spring or early summer planting.

Useful information
-
Soak the Iris ensata 'Imperial Burgundy' roots in water for 3-6 hours prior to planting
Plant your "Japanese water iris" bare roots into temporary pots with a multipurpose compost within a week of delivery and grow-on in a sheltered spot outdoors
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
