Jack Frost Brunnera (Brunnera macrophylla ‘Jack Frost’) is a herbaceous perennial that has green, heart shaped foliage overlaid with a silvery lacework pattern. Small, light blue flowers rise above the foliage and add even more color in the spring. This plant can be used en masse to create a bright groundcover or used as an accent plant throughout the garden.

They prefer cool sites with rich, well-drained soils and to be sheltered from intense sun. It’s best to place in full shade to filtered sun and water regularly to keep the soil evenly moist. As old foliage starts to fade, remove it before the new leaves emerge to keep the plant looking tidy.

Jack Frost Brunnera grows slowly to reach 12 inches tall and spreads to about 24 inches wide. The blooms can reach up to 18 inches tall.

Other notable cultivars of Brunnera include, but not limited to, ‘Looking Glass’, ‘Silver Heart’, ‘Variegata’, and ‘Emerald Mist’.
