About
Brunnera macrophylla 'Jack of Diamonds' PBR is a deciduous perennial characterized by its substantial, textured, heart-shaped to rounded leaves that exhibit a silvery hue with prominent dark green veins. The leaves can reach lengths of up to 25 cm and cluster at the base, creating a dense foliage mound that can expand to 80 cm in width. In the spring, clusters of small, vibrant blue flowers emerge above the leaves, adding a splash of color to the plant's overall appearance.
