Brunnera macrophylla ‘Jack Frost


Extra notes and interesting information:
Brunnera is useful as an informal ground cover under high-branching deciduous trees; among spring-flowering shrubs such as forsythia, deciduous magnolias; as filler between newly planted evergreen shrubs.  Freely self-sows once established.  Increase by dividing clumps in fall.
