Discover how to grow stunning Brunnera flowers (like Jack Frost!), their hidden meanings, and companion planting ideas. Perfect for shade gardens—written by expert gardener Ashley Scott.
Hi there! I’m Ashley Scott, and over my 10 years of gardening, Brunnera flowers have become one of my go-to plants for shady corners. With their heart-shaped leaves and delicate blue blooms, these perennials add magic to any garden. Let’s dive into everything you need to know about growing Brunnera, their symbolism, and how to make them thrive—even if you’re a beginner!
What Are Brunnera Flowers?
Brunnera macrophylla, commonly called Siberian Bugloss or Heartleaf Brunnera, is a shade-loving perennial native to Eastern Europe and Asia. Its charm lies in two features:
- Foliage: Large, textured leaves (often silver-veined or speckled).
- Flowers: Tiny, sky-blue blooms that resemble forget-me-nots.
I first fell in love with Brunnera when I planted ‘Jack Frost’—a variety with icy silver leaves that glow in dark corners. But there’s so much more to explore!
Top Brunnera Varieties to Try
1. Brunnera ‘Jack Frost’
This superstar variety has silvery leaves with green veins. In spring, it produces blue Brunnera flowers that contrast beautifully with the foliage. It’s deer-resistant and thrives in Zones 3-8.
Pro Tip: Pair it with dark-leaved heucheras for a dramatic effect!
2. Brunnera ‘Alexander’s Great’
A larger version of ‘Jack Frost,’ with leaves up to 15 inches wide. Its white Brunnera flowers add elegance to woodland gardens.
3. Brunnera ‘Silver Heart’
Glossy, heart-shaped leaves with a frosty sheen. The blue flowers pop against the metallic foliage.
4. Brunnera ‘Looking Glass’
Nearly all-silver leaves that brighten shady spots. I’ve used this in bouquets—yes, Brunnera flower bouquets are a thing!
How to Grow Brunnera Flowers: A Step-by-Step Guide
Planting Brunnera
- When: Early spring or fall.
- Where: Partial to full shade (morning sun is okay).
- Soil: Moist, well-draining soil rich in organic matter.
I once planted Brunnera seeds in clay soil—big mistake! They rotted within weeks. Stick to divisions or nursery plants for better success.
Watering & Feeding
- Keep soil consistently moist (not soggy).
- Mulch to retain moisture.
- Fertilize lightly in spring with compost.
Sunlight Needs
Too much sun scorches their leaves. My Brunnera macrophylla thrived under my maple tree but wilted in a sunny border.
Brunnera Flowering Time & Colors
When do Brunnera flower? Typically mid-spring to early summer (April–June). In cooler climates, blooms may last longer.
- Colors: Mostly blue, but some varieties like ‘Queen of Hearts’ have pink-tinted blooms.
- Symbolism: Brunnera symbolizes humility and everlasting love—perfect for a Brunnera flower bouquet!

Are Brunnera flowers edible? No—they’re not toxic, but not meant for eating.
