It’s the remarkable leaves that catch your eye, large and heart-shaped, their silvered surface almost mirror-like. That will do for starters, indeed for most of the year, but in the early summer (and often later) you also get sprays of bright blue flowers in the style of forget-me-nots. A newly introduced variety, tougher than Looking Glass. Prefers some shade. Fertile, moist but well-drained soil. 12 in. 2 litre Pot.

Brunnera Macrophylla Silver Heart is a hardy perennial plant with silver veined heart shaped leaves and blue forget me not flowers in spring suitable for shade.
