Brunnera 'Jack Frost' is a reliable herbaceous perennial grown mainly for its bold silver leaves marked with green veins. In spring, it carries clusters of small blue flowers that rise above the foliage and bring a soft, fresh look to shady areas. The plant forms a neat clump and works well in woodland borders, under shrubs, and in containers.
Its bright foliage helps lighten darker parts of the garden through spring, summer, and into fall. It is a strong choice for ground cover in moist, well-drained soil and is also helpful in pollinator planting because the flowers attract bees. Deer and rabbits usually leave it alone, which adds to its value in low-maintenance planting.
This plant needs little pruning beyond removing faded flower stems and tired leaves. Propagation is usually done by division, which is the easiest and most dependable method for home gardeners. It is mostly healthy, though slugs, snails, and occasional mildew can appear, especially when growing conditions are poor.
