This is a wonderful plant, and it's great to see it win the 2012 Perennial Plant of the Year from the Perennial Plant Association. It's Brunnera macrophylla 'Jack Frost,' good for our hardiness zone and excellent in shade.
It has tiny blue forget-me-not blossoms that create a cloud effect on frosty silver leaves. Recommended uses include in front of a shady border, in containers, and in a perennial bed with hostas, ferns and epimediums. It's outstanding paired with Japanese painted fern.
I've used 'Jack Frost' in containers and even after it's done blooming (mid- to late spring), the leaves are so extraordinary the plant remains eye-catching all summer long.
It grows about a foot tall (the flowers make it seem taller) and can spread 20 inches or so. Makes a nice mound.
Steven Still, head of the Perennial Plant Association, says 'Jack Frost' was selected because it's "outstanding and easily grown." Simple and true.
