A sight to behold! The leaves of 'Jack Frost' are intricately detailed with a crackle-like finish. Though the leaves are dark green, they have a heavily frosted overlay which allows only the green veining to show through. From mid to late spring, baby blue, forget-me-not type blossoms are held in clusters several inches above the shimmering foliage. The effect is breathtaking.
Tip for southern growers and gardeners: 'Jack Frost' tolerates heat better than the older brunnera cultivars.
Brunneras are classic perennials that are treasured for their shade tolerance and lovely blooms. They make a fantastic groundcover, though the variegated forms may be slower to spread than the species. Try growing them in containers too so they will be close at hand when you want to snip a few blooms for a spring bouquet.

Brunnera is a woodland plant that should be grown in full shade and consistently moist soil in southern regions. In the north, morning sun is acceptable as long as the soil remains moist. They will grow the fastest and strongest in rich soil.
Little care is needed once Brunnera is established. Cut back the old foliage in the spring rather than in the fall; it will help to protect the crown during the winter. A winter mulch is also recommended.
