Easily grown in average, medium moisture, well-drained soil in part shade. Intolerant of dry soils. Prefers consistently moist, organically rich soils in shady areas. Clumps slowly spread by both creeping rhizomes to form thick ground covers.
Siberian bugloss is a rhizomatous, clump-forming perennial that is primarily grown for its attractive basal foliage. ‘Jack 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. ‘Jack Frost’ is a sport of non-patented Brunnera marcrophylla ‘Langtrees’. 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.
