Brunnera
Brunnera macrophylla
flowerBrunnera (Brunnera macrophylla), or Siberian bugloss, is a rhizomatous, clump-forming shade perennial about 1 to 1.5 ft tall and a bit wider. In early to mid-spring it floats airy sprays of tiny blue, white-eyed flowers that look just like forget-me-nots above bold, heart-shaped leaves. The plain green species is handsome, but the silver-patterned cultivars such as Jack Frost are the real prize, lighting up shady corners with metallic foliage from spring through fall. It is deer and rabbit resistant and an excellent groundcover for moist shade.

🌱 Growing Guide
Grow brunnera in partial to full shade with protection from afternoon sun, in fertile, consistently moist, well-drained soil; it is intolerant of dry soil, where the leaves scorch. Keep it evenly moist and mulch to hold moisture and keep roots cool. It is an easy, low-maintenance plant in the right spot but does poorly in the heat and humidity of the deep Southeast. Cut back any tired or scorched foliage in summer to flush fresh leaves. Propagate by division in spring or fall; note that named silver cultivars are often patented, so propagate only for personal use.
🌼 Have a different variety?Cultivars of the same species usually share the same basic care, and they differ mainly in flower color, height, and bloom form, not in how you grow them. So this guide still applies even if your exact variety isn't the one shown.

🌸 Blooms & cutting
Brunnera is grown as a foliage groundcover, not for harvest. The main task is to shear off any scorched or tattered leaves in summer to bring on a fresh flush, and to divide clumps in spring or fall to renew them and spread the planting. The delicate flower sprays can be cut for tiny arrangements.
🥗 Nutrition & benefits
Brunnera is an ornamental, not edible. Its value is long-season silver foliage and early blue flowers that brighten moist shade, plus a tough, deer-resistant, weed-suppressing habit. Have a different variety? Cultivars of the same species share the same basic care, so this guide still applies even if your exact leaf pattern is not shown.
