Brunnera macrophylla 'Jack Frost'

Brunnera macrophylla 'Jack Frost' is a very attractive perennial for shade.  The heart-shaped leaves are mostly a silvery-white, but with green veins.  It's eye-catching.  I think it's not gaudy, but probably too bright for some.  The small, bright-blue flowers come in May.  They are pretty, but bloom is usually not very dense.  The plant forms a mound about 2 feet wide fairly quickly, but does not seem to exceed that.  When in flower, it reaches 2 feet tall.  It disappears in winter.  Brunnera macrophylla is native to the Caucasus, Georgia & Turkey in forests & on grassy slopes.  The common name is Siberian Bugloss.  Brunnera macrophylla is better in part shade than deep shade.  It needs moderate water in summer & tolerates some wetness in winter.  Use it in a shaded perennial border, or between shrubs under trees.
