Brunnera — 7 species
Part of the Borage & forget-me-nots family (Boraginaceae)
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.

Brunnera — frequently asked questions
Are Brunnera plants toxic to cats and dogs?
Most Brunnera are not pet-safe. Of the 7 Brunnera species in the Growli library, 6 (86%) carry a toxic or mildly-toxic ASPCA classification and 1 are pet-safe. Always confirm the exact species on its pet-safety page before trusting it around cats or dogs.
How much light do Brunnera plants need?
Most Brunnera do best in medium indirect light. If yours stretches toward the window or loses its variegation it wants more light; scorched or bleached leaves mean it is getting too much direct sun.
Are Brunnera easy to care for?
Some Brunnera suit more experienced growers — several want strong light, sharp drainage or a specific seasonal rhythm. Check the individual species page for the exact regime.
