In early spring, large, mid-green, heart-shaped leaves that look as though they have been dusted with silver appear, followed by tall sprays of tiny, bright blue, forget-me-not-like flowers.

For the best variegation, a sheltered, shady site is essential. Although it prefers moist conditions, brunnera will tolerate dry soil once established, and will spread to form a large clump.

Brunnera macrophylla 'Jack Frost' is a gorgeous groundcover plant for the front of a border, or lighting up moist, shady areas under the canopy of deciduous trees, or for edging a woodland path.


  • Garden care:
    Incorporate a generous amount of composted organic matter or well-rotted manure into the backfill during planting, but choose a shady spot to preserve the vibrant foliage.

    Water newly planted perennials regularly for their first year to encourage successful establishment, providing extra water during long dry spells.

    Apply a mulch of garden compost or well-rotted manure to the soil surface annually in spring to enrich the soil. Remove spent flower spikes after the last bloom has faded.

    Once established and if desired, lift and divide the plant every two or three years in late autumn.
