IRIS TECT. CRUELLA

Overview & Features

• Iris tectorum ‘Cruella’ is a striking dwarf iris known for its bold bi-coloured flowers.

• Features large white blooms dramatically marked with deep purple to near-black falls.

• Flowers appear in late spring, creating strong visual contrast in the garden.

• Forms compact clumps of sword-shaped green foliage.

• Typically grows to 20–30 cm in height.

• Ideal for rockeries, raised beds, gravel gardens, and the front of borders.

• Excellent for container planting in sunny positions.

• Attractive to bees and pollinators.

This variety is valued for its dramatic colouring and compact, manageable size.

Planting & Positioning

• Plant in full sun for the best flowering performance.

• Tolerates light partial shade, though flowering may be reduced.

• Prefers well-drained soil and does not tolerate prolonged winter wet.

• Thrives in moderately fertile soil enriched with organic matter.

• Improve heavy soils with grit to enhance drainage.

• Plant rhizomes so the top is just visible at the soil surface.

• Avoid burying the rhizome too deeply, as this can prevent flowering.

• Space plants approximately 25–30 cm apart to allow clump development.

Iris tectorum performs best in sunny, sheltered areas with good drainage.

Watering, Feeding & Flowering

• Water regularly during the first growing season to establish roots.

• Keep soil moderately moist during active growth in spring.

• Avoid waterlogging, particularly in winter months.

• Feed lightly in early spring with a balanced fertiliser to encourage flowering.

• Avoid high-nitrogen fertilisers, which may promote foliage over blooms.

• Flowering typically occurs in late spring.

• Remove spent blooms promptly to maintain a tidy appearance.

Good sunlight and proper rhizome planting depth are key to reliable flowering.

Pruning, Maintenance & General Care

• Remove faded flower stems after blooming.

• Cut back yellowing or damaged leaves as needed.

• Divide clumps every 3–4 years after flowering to maintain vigour.

• Ensure rhizomes remain partially exposed to sunlight.

• Apply a light mulch in winter, keeping it away from the rhizomes.

• Generally low maintenance and resistant to most pests and diseases when well positioned.

• Protect from excessive winter wet rather than frost.

With full sun, well-drained soil, and correct planting depth, Iris tectorum ‘Cruella’ will provide dramatic late spring colour and reliable garden performance year after year.
