Brunnera Brunnera
Brunnera macrophylla
Brunnera is one of the most reliable answers to the shaded Fairview border; tiny forget-me-not flowers cover it in early spring, and then the large, heart-shaped leaves take over for the rest of the season. The silver-splashed cultivars brighten dark corners in a way that almost nothing else manages.

The Early Blue in the Shade
The early part of spring at The Patient Garden belongs to plants that thrive in the shadows. Most of our beds face varying amounts of shade from surrounding trees, and brunnera has become one of our most dependable answers to that challenge. In late March and April it produces clouds of tiny blue flowers on wiry stems held above the foliage; the flowers are nearly identical to forget-me-nots, small and sky-blue with a yellow eye. But brunnera is a perennial that comes back reliably, year after year, without the weedy reseeding that makes true forget-me-nots a management problem in some gardens.
The common name Siberian bugloss is accurate about the origin but rarely used. Most gardeners know this plant as brunnera or heartleaf brunnera, which describes the foliage precisely. The leaves are large, rough-textured, heart-shaped, and deeply veined, and they expand considerably after the flowers fade, covering the ground with a broad, lush mat through summer and fall.
The Foliage Is the Point
This is one of the few plants where the flowers are almost secondary. The blooms are delightful, a reliable early-season blue that pairs beautifully with tulips, hellebores, and spring bulbs. But the foliage carries the plant through the rest of the year.
Species brunnera has dark green leaves with a slightly rough, textured surface. It looks sturdy and almost architectural when fully expanded. But the cultivars with silver-splashed leaves are what most gardeners encounter at nurseries today, and they earn the attention. 'Jack Frost' covers nearly the entire leaf surface in silver with just the veins remaining green, creating a mirrored effect in the shade that brightens dark corners considerably. 'Looking Glass' is similar but even more silver. 'Diane's Gold' offers gold-toned foliage for a warmer effect in filtered light.
The silver forms can scorch in direct afternoon sun, especially in warm summers. At Fairview, where surrounding trees create varying degrees of light, the bright-silver forms do best in the most sheltered spots while the straight species handles a wider range of exposure.
Growing on Fairview Clay
Brunnera is native to moist woodland margins in eastern Europe and the Caucasus, which turns out to describe a shaded Willamette Valley garden fairly well: cool, moist winters and springs, filtered light under deciduous trees, and soil that retains moisture through summer. Our heavy clay actually helps here. It holds moisture through the dry season, which keeps brunnera from going prematurely dormant in a way that fast-draining sandy soil would not.
This is one of the few plants where Fairview clay is genuinely an asset rather than a problem to manage. Brunnera in sandy or fast-draining soil tends to look tired by July. On our clay, with some supplemental water through August, it stays fresh and full until frost.
Plant it in shade to part shade. More than a few hours of direct summer sun stresses the plants, particularly the silver-leaved cultivars. Morning sun with afternoon protection is usually fine and produces the best combination of healthy foliage and good flower production.
Year by Year
Brunnera is slow to establish in its first year. Plant in fall or early spring, water consistently, and expect modest growth. By year two, the crown begins to expand and the foliage becomes more impressive. By year three or four, a well-sited brunnera is a dependable, handsome presence that mostly takes care of itself.
Divide plants every three to four years when the center begins to die out or the clump becomes overcrowded. Division is best done in early spring as growth resumes, or in early fall. Divisions establish quickly and can be moved to new spots around the garden or shared with neighbors.
Brunnera does not spread aggressively by runners or rhizomes. It stays roughly where you put it, expanding gradually from the center outward. The species forms can self-sow mildly in favorable conditions, producing seedlings near the parent plant. Named silver cultivars do not come true from seed.
Native Status and Behavior
Brunnera macrophylla is not native to the Pacific Northwest. It is from eastern Europe and western Asia, and it does not become invasive in our conditions. It stays in its planted spot, does not spread underground, and self-sows only modestly if at all. It is a well-behaved addition to the shade garden.
Pollinators and Companions
The early blue flowers attract small bees and native pollinators in April, when the number of blooming plants in the shaded garden is still limited. The contribution is modest compared to full-sun plants with larger flowers, but for a shade garden in early spring it matters.
In The Patient Garden, brunnera grows alongside hellebores, ferns, and the early spring bulbs that share the shaded beds along the north edge of the main border. The blue flowers align beautifully with hellebore blooms in late March, and the expanding foliage fills the gaps left when spring bulbs go dormant. Later in summer, hostas and shade-tolerant sedges provide company.
The combination of silver brunnera foliage, fern fronds, and the occasional shaft of light breaking through the canopy is one of the quieter pleasures of the shaded garden at Fairview.
