Growing Conditions

Light:
Prefers partial to full shade. Can tolerate morning sun if soil remains consistently moist. Best colouring and performance in dappled or light shade.

Soil:
Thrives in moist, humus-rich, well-drained soil. Prefers neutral to slightly acidic conditions. Avoid dry, sandy, or waterlogged soils.

Exposure:
Best in sheltered spots, protected from strong sun and drying winds. Hardy across the UK, withstanding severe winters.

Drought Tolerance:
Low drought tolerance. Requires regular moisture, especially in sun or during dry periods. Mulch to help retain soil moisture.

Cultivation & Care

Planting Time:
Best planted in spring or autumn when soil is moist and temperatures are moderate.

Spacing:
Space plants approximately 30–45 cm (12–18 inches) apart. Mature height typically reaches 20–30 cm (8–12 inches) tall with a spread of 30–45 cm.

Watering & Fertilisation:
Water regularly in dry spells. Apply a balanced fertiliser in early spring to encourage healthy foliage and abundant flowering.

Mulching & Pruning:
Mulch in spring with compost or leaf mould to retain moisture and enrich the soil. Cut back old or damaged leaves after flowering to encourage fresh growth.

Propagation:
Propagate by division in early spring or after flowering in late summer. Easy to divide and replant to expand coverage.

Seasonal Interest

Spring:
Produces clusters of vivid deep blue flowers in early to mid-spring—one of the truest blue pulmonarias. Leaves emerge fresh green, forming a dense clump.

Summer:
After flowering, maintains attractive green foliage. Leaves may develop slight spotting but are less marked than other cultivars.

Autumn:
Foliage gradually declines. In mild climates, some leaves may persist; otherwise, it begins to die back.

Winter:
Semi-evergreen to deciduous depending on the climate. In cold areas, foliage dies back completely and regrows in spring.

Wildlife & Garden Use

Wildlife:
Flowers attract early pollinators, including bees. Valuable nectar source in early spring when few other plants are blooming.

Garden Use:
Ideal for shaded borders, woodland gardens, or underplanting shrubs. Great for groundcover in part-shade and pairs well with spring bulbs.

Companion Plants:
Pairs well with:

• Helleborus

• Brunnera

• Tiarella

• Ferns (e.g., Dryopteris, Polystichum)

• Epimedium

Works beautifully in mixed shade plantings, providing early spring colour and lush groundcover beneath taller perennials or shrubs.
