Heartleaf Alkanet

Brunnera macrophylla 'Alexander's Great' PP025789, COPF

A specimen perennial that forms a gigantic mound of unusually large, heart-shaped, heavily silvered leaves. Sprays of forget-me-not flowers bloom in early spring.

A superb specimen perennial, forming a gigantic mound of very large, heart-shaped, heavily silvered leaves. Sprays of blue Forget-me-not flowers appear in spring. This selection makes a dynamic statement in the woodland garden. Keep out of hot afternoon sun, as the leaves can scorch. Plants may be divided easily in early autumn. Sometimes self seeds generously, but usually the seedlings have plain green leaves. A 2013 introduction by Terra Nova Nurseries, Oregon. USPP#25789: unlicensed propagation prohibited.
