Easily grown in average, medium moisture, well-drained soil in part shade. Prefers consistently moist, organically rich soils in shady areas. Generally intolerant of dry soils, but tolerates some dryness better than most other cultivars of this species. Foliage may scorch in hot summer sun. Plants prefer cool summers, and generally will not perform well in the hot and humid summer conditions of the deep South (USDA Zones 7-9). Clumps slowly spread by creeping rhizomes to form thick ground covers. Plants may self seed in optimum growing conditions, but seedlings of variegated forms may not come true (may lose variegation).

Noteworthy Characteristics

Brunnera macrophylla, commonly called Siberian bugloss, is a rhizomatous, clump-forming perennial that is primarily grown in shady areas for its attractive heart-shaped, dark green, basal foliage. Small, blue, forget-me-not-like flowers with white centers bloom in airy, branched racemes rising well above the foliage on slender stems to 18" tall in spring. Basal leaves form a foliage mound which remains attractive throughout the growing season. Smaller upper leaves are elliptic.

Brunnera macrophylla is synonymous with and sometimes sold as Anchusa myosotidiflora.

Genus name honors Swiss botanist Samuel Brunner (1790-1844).

Specific epithet from Latin means large leaved.

Common name of bugloss comes from Greek meaning ox tongue in probable reference to the roughness and shape of the leaves.

‘Spring Yellow’ is a yellow-leaved cultivar. Yellow, heart-shaped basal leaves (3-5” wide) emerge in spring to form a hosta-like foliage mound to 15" tall. Smaller stem leaves are elliptic. Yellow leaves acquire some green tones as the growing season progresses. Leaves may turn primarily green if plants are grown in full shade. Tiny, forget-me-not-like, blue flowers in airy, branched, paniculate cymes rise slightly above the foliage on slender stems in spring. U.S. Plant Patent Applied For (PPAF).


No serious insect or disease problems. Slugs and snails are occasional visitors.
