Queen of Hearts Siberian Bugloss (Brunnera macrophylla 'Queen of Hearts')
brun-ERR-ah mak-roe-FY-lah 'Queen of Hearts'

Deciduous Perennial Mounded in the Boraginaceae Family
A Walters Gardens Siberian Bugloss bred for extra-large, heart-shaped silver leaves and improved heat tolerance -- 'Alexander's Great' crossed with a 'Diane's Gold' seedling.

Brunnera macrophylla 'Queen of Hearts' (US Plant Patent 32,737) was bred by Hans A. Hansen at Walters Gardens from a 2015 cross using 'Alexander's Great' as the female parent and an unnamed seedling of 'Diane's Gold' as the male parent. The result is a vigorous plant with very large, heart-shaped leaves -- densely silvered between the veins, with narrow dark green tracing the veins themselves -- on notably thick foliage that resists sun scorch better than many older Brunnera selections.

Light blue flowers bloom on tall stems well above the foliage for about four weeks each spring. 'Queen of Hearts' is hardy to USDA Zone 3 and forms a substantial, well-behaved mound.

Pros

  • Very large, heart-shaped leaves with dense silver and fine dark green veining
  • Improved heat tolerance compared to older Brunnera selections
  • Deer resistant and shade tolerant
  • Hardy to USDA Zone 3

Cons

  • Needs consistent moisture, especially in its first season
  • Foliage can scorch if grown in too much direct sun
  • Its large size needs more room than compact siblings like 'Jack Frost'
Highlights Foliage of Interest Heat Tolerant Deer Resistant

Field-Grown vs. Greenhouse-Grown Plants

Plants which are well-adapted to our local climate are most often field-grown (outside). Field-grown plants are generally cheaper and have the advantage of already somewhat acclimated to our cold winters, but that means they’re not artificially far along in the spring and tend to bloom at the normal time in our area.

Spring annuals and tender perennials are typically grown in Greenhouses so they can be ready and luxurious exactly when customers want them. Some perennials are also “forced” into early bloom in greenhouses. In May, there can be a very big difference between field-grown and greenhouse-grown plants of the same type. The latter typically look good right away (so they’re a great choice where that’s important), but we typically pay a premium for it.

No Pricing or Availability Right Now

We order from a rotating cast of the best nurseries in the Great Lakes region. It looks like we've offered this plant in the past, but the nurseries we're working with this week don't appear to have it in stock at the moment.

Our goal is to bring as many plants together under "one roof" as possible, so we'll try hard to make it available again in the future!
