Brunnera macrophylla 'Sterling Silver'

Brunnera macrophylla 'Sterling Silver'
  'Sterling Silver' is an improvement from 'Looking Glass' with the same stunning silver color and heart-shaped foliage, but with larger leaves (7-8" wide) and larger habit, better leaf quality, and increased heat tolerance. In early spring, multitudes of tiny blue, forget-me-not flowers appear above the foliage. 10-14". Z3-8.
