Brunnera macrophylla Jack Frost

Brunnera Jack Frost is a true gem for the spring garden, its heart-shaped leaves exquisitely frosted with silver and etched with delicate green veins. In early spring, clouds of tiny, forget-me-not-blue flowers rise gracefully above the foliage, creating a charming contrast that lasts for weeks. Even after flowering, the striking leaves remain a focal point, lighting up shady borders, woodland gardens, and pots with their luminous sheen. Hardy and reliable, Jack Frost thrives in partial to full shade, bringing elegance to those often-overlooked garden corners. A plant of year-round beauty, it offers both enchanting spring blooms and exceptional foliage interest.

Planting Instructions

Brunnera macrophylla ‘Jack Frost’ is a hardy perennial grown for its striking heart-shaped silver leaves with green veining and sprays of small, forget-me-not–blue flowers in spring. Ideal for brightening shady areas of the garden.

When to Plant:
Plant in spring or early autumn, avoiding frozen or waterlogged ground.

Where to Plant:
Thrives in partial to full shade in moist, fertile, well-drained soil. Perfect for woodland gardens, shaded borders, or underplanting shrubs.

How to Plant:

• Depth: Plant so the crown is level with the soil surface.
• Spacing: 40–45 cm (16–18 inches) apart to allow for spread.
• Tip: Water thoroughly after planting to help roots establish.

Aftercare:
Water regularly during dry spells in the first season. Mulch annually in spring to conserve moisture and enrich the soil. Remove faded flower stems after blooming and tidy away old leaves in late autumn to make way for fresh spring growth.

Top Tip:
Plant ‘Jack Frost’ alongside spring bulbs, hostas, or ferns — its silver foliage provides a beautiful contrast and keeps borders looking fresh long after the flowers have faded.
