Unpack bare roots or rhizomes on arrival and plant them within a week. Until then, keep them somewhere cool and ensure the roots remain slightly moist, never wet.

Iris ensata
'Imperial Burgundy'
Japanese water iris
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.

Plant calendar
Remove the packaging straight away, check the compost and water thoroughly if dry. Check the plant’s hardiness before placing it outdoors. Plant into a border or permanent container within a month, choosing the position recommended for the variety. Keep the top of the root ball level with the surrounding soil, firm gently and water well.
Soak the roots in water for three to six hours immediately before planting. Keep any crown, buds or emerging shoots above the water where possible.
Pot most bare roots into 15–20cm pots filled with peat-free multipurpose compost. Large or depth-sensitive roots, including peonies, are often best planted directly into borders.
Arrange the roots naturally without bending them. Cover the roots completely, positioning the crown and buds at the depth recommended for that particular perennial.
Keep pots in a sheltered outdoor position and water whenever the compost begins to dry. Grow on until roots hold the compost together when lifted from the pot.
Plant into a suitable border or permanent container once well rooted. Add a label and water regularly throughout the first growing season while the perennial establishes.
