Queen of Hearts is a shade perennial grown mostly for its leaves: broad, heart-shaped foliage washed almost entirely in silver, with a fine network of green veins showing through. It brightens dim corners under trees and along north-facing walls all season long.
In mid to late spring, airy sprays of tiny sky-blue flowers rise above the leaves, a lovely match for early bulbs and ferns. The clump reaches about 16 to 18 inches tall and spreads 2 to 3 feet, making it a good choice for massing, edging a woodland path or planting in a shaded container.
What it looks like
A broad, low mound of large heart-shaped leaves, each 5 to 7 inches across, covered in a bright metallic silver sheen with thin dark green veins and a narrow green rim. The leaves have a slightly quilted, matte texture and overlap to form a dense clump about 16 to 18 inches tall and up to 3 feet wide. In mid to late spring, branched wiry stems rise to about 2 feet and carry loose clusters of tiny five-petaled flowers, each about a quarter inch wide, in soft sky blue with a small white-yellow eye. At peak bloom the blue flowers float like a haze above the silver foliage.
Growing it with lavender
Brunnera wants shade and steady moisture, unlike lavender, so plant it in a cool, shaded bed under trees or on the north side of a building.
Care
Grow in part to full shade in average to rich soil that stays evenly moist; protect from hot afternoon sun, which can scorch the leaves. Hardy in zones 3-8. Trim off faded flower stems after bloom to keep the foliage looking tidy.
