Ideal Growing Conditions

Light

• Partial shade is ideal, especially dappled or morning sun with afternoon shade.
• Avoid hot midday sun in dry situations.

Soil

• Moist, fertile, humus-rich soil that never dries out.
• Excellent in boggy, damp spots, beside water features, or in moisture-retentive woodland loam.

Moisture

• Keep consistently moist; thrives in areas that naturally stay damp.
• Mulch yearly to preserve soil moisture.

Temperature & Hardiness

• Hardy and reliable across the UK; enjoys cool conditions.
• Handles wet winters well, provided soil doesn’t stagnate anaerobically.

Planting & Spacing

• Best time: Spring or early autumn.
• Spacing: 30–45 cm (12–18″) to allow the rosettes to expand naturally.
• Plant crowns level with soil surface—avoid burying too deeply.

Care & Maintenance

Watering

• Regular watering in dry spells is crucial.
• Irrigate at soil level to reduce leaf wetness.

Feeding

• A light, balanced feed in spring supports strong flower stem production.

Deadheading & Tidying

• Remove spent tiers to encourage neatness, or leave them for seed if self‑seeding is welcome.
• Clear away old leaves after flowering to keep the rosette fresh.

Dividing

• Divide every 2–3 years in early spring or autumn to rejuvenate clumps and ensure flowering vigour.

Wildlife Value

The pure-white flowers provide nectar and pollen for bees, hoverflies, early butterflies, making it a subtle but important contributor to a wildlife-first spring garden.

Where It Shines in the Garden

• Pond margins & slow streams
• Damp woodland edges
• Shaded bog gardens
• Cool, moisture-retentive mixed borders
• Naturalised drifts under deciduous trees
