Brunnera — 7 species

Brunnera is a compact shade-loving perennial grown primarily for its striking heart-shaped leaves — cultivars like 'Jack Frost' and 'King of Hearts' feature silver-frosted foliage that brightens dark corners from spring through autumn. It thrives in partial to full shade and prefers consistently moist, well-drained soil rich in organic matter; avoid letting it dry out in summer. All Brunnera species are toxic to cats and dogs, so keep them out of reach of pets.
