Noteworthy Characteristics:
Siberian bugloss is a rhizomatous, clump-forming perennial that is primarily grown for its attractive basal foliage. 慗ack Frost?leaves are a distinctive silvery white with green primary and secondary veins and a thin green rim around the leaf edges. The basal foliage forms a hosta-like mound of heart-shaped leaves (3-5?wide) which remain attractive throughout the growing season. Smaller stem leaves are elliptic. Tiny, forget-me-not-like flowers (light blue with yellow centers) in airy, branched paniculate cymes rise above the foliage on slender stems to 18?tall in spring. 慗ack Frost?is a sport of non-patented Brunnera marcrophylla 慙angtrees? Species is synonymous with and sometimes sold as Anchusa myosotidiflora. Bugloss comes from Greek meaning ox tongue in probably reference to the roughness and shape of the leaves. U. S. Plant Patent PP13,859 issued June 3, 2003.
No serious insect or disease problems. Slugs and snails are occasional visitors.
