Brunnera macrophylla

About

Brunnera macrophylla, the Siberian bugloss, great forget-me-not, largeleaf brunnera or heartleaf, is a species of flowering plant in the family Boraginaceae, native to the Caucasus. It is a hardy, rhizomatous, herbaceous perennial, that can reach from 12 to 18 inches in height, and carries basal, simple cordate leaves on slender stems. Sprays of small blue flowers, similar to those seen in the related forget-me-nots, are borne from mid-Spring, and bloom for eight to ten weeks.
