Jack Frost Brunnera

Brunnera macrophylla ‘Jack Frost’ forms a low mound of heart-shaped leaves with a frosted silver surface and green veins, followed by airy sprays of small light-blue, forget-me-not-like flowers in spring. This shade perennial works as a border accent or groundcover and keeps its foliage attractive when moisture is adequate. ## Foliage and flowering The [CNB New Plants profile](https://cnbnewplants.nl/en/assortment/perennial-plants/jack-frost) identifies the cultivar as Brunnera macrophylla ‘Jack Frost’, with silver-gray leaves, blue flowers, and April-to-June flowering. The [University of Wisconsin Extension profile](https://hort.extension.wisc.edu/articles/brunnera-macrophylla-jack-frost/) describes a rounded mound about 1½ feet tall and wide, with flowers for several weeks in mid-spring. It notes that dry conditions can cause brown, tattered foliage. ## Siting and care Plant in partial shade, ideally with morning light and afternoon shade, in moist, well-drained soil. Water during dry periods and mulch to conserve moisture. Wisconsin Extension lists USDA hardiness zones 3a–8b. Walters Gardens gives a compact 12–15 inch height and spread; provide partial shade and steady moisture to protect the foliage. ## Maintenance Remove spent flower stalks if a tidier appearance is wanted, though this is not required. Cut away tattered leaves as needed, leaving old foliage in place over winter and removing it as spring growth begins.
