Clump-forming, spring flowering, herbaceous perennial, mainly grown for its attractive basal foliage. Slowly spreading by creeping rhizomes. Large, heart-shaped, silvery white leaves with green veins and margins. Small, light blue, forget-me-not-like flowers, held above the foliage on 20-50 cm long stalks. Foliage is evergreen in mild climates, but in colder regions, the leaves die back from late autumn.
Ideal for a position where it receives morning sun and afternoon shade, but will also grow in full shade. Brunnera macrophylla 'Jack Frost' handles more sun than most other variegated brunneras, but in regions with hot summers, leaves may be scorched by afternoon sun. Prefers consistently moist, but well-draining, rich soils, and is not tolerant of dry conditions. Frost-hardy. For a tidy appearance, remove old or damaged leaves if present, just before the new foliage appears. Self-seeds, but seedlings may turn out different from the parent plant, and may even have lost the silvery leaf colour variegation. Can be divided in spring or autumn.
Excellent choice for the woodland garden. Lovely companion for other shade-loving plants such as hostas and ferns, for spring-flowering bulbs, or for dark-leafed plants such as black mondo grass (Ophiopogon planiscapus 'Nigrescens'. Good ground-covering and edging plant.
