Brilliant blue in early spring
The brilliant blue flowers are very welcome in early spring, and look wonderful with miniature Daffodils blooming amongst them.
But for me, it is the wonderful silver, heart shaped leaves that really capture my affections.
With their deep green veins standing out so boldly against a silver background.
A hardy new and much improved Brunnera
Brunnera macrophylla ‘Sea Heart’ can tolerate more sun and periods of dry than some older cultivars. And it is less susceptible to scorch when it does catch the sun.
As well it has enhanced resistance pests or disease, due to its thicker textured leaves.
This wonderful new cultivar was a chance discovery, by a sharp eyed nurseryman, in the Netherlands in 2010. And it has quickly stolen gardening hearts around the world.
Shining silver groundcover for shade
However Brunnera macrophylla ‘Sea Heart’ is really ideal as a foliage feature, edging plant along a path, or ground-cover in Deep to Part Shade. It can prosper in low light levels.
So it is perfectly happy under trees and shrubs, or in deeply shadowed areas between buildings.
Where it is surprisingly tolerant of occasional dry spells and splashes from the sun.
And it positively glows and lights up any gloomy area.
Growing: Brunnera macrophylla ‘Sea Heart’
– Height with flowers: 30cm approx.
– Width: Ever-silver, neat foliage clump to a diameter of 20cm – 40cm approx.
– Position: Deep Shade, as well as Partial Shade and Dappled Sun.
– Soil: Brunnera thrive with mulch, and can tolerate most soil types.
They are robustly easy in loam and clay based soils opened up with organic matter.
And they can even prosper in sandy soils, as long as they are well mulched.
They are serene in a range of soil pH, from the acid to the alkaline lime side of neutral.
– Frost: Hardy
– Water: Normal average garden watering satisfies Brunnera. And they certainly respond well to mulch and compost, which helps even out the moisture content in the soil.
They can tolerate short periods of dry between drinks, and this extends out when they are well mulched.
– Growth: Neat, shining, evergreen (ever-silver) perennial clump.
– Beneficial for wildlife: Bees and other beneficial insects are attracted to the small but vivid, bright blue blooms. Our bees certainly appreciate the flowers so early in the spring.
– Care: Low maintenance. So simply remove spent flowers and any old leaves after flowering. Otherwise they can just be left alone to get on with their job of glowing with silver in dark areas.
– Deer & Rabbit resistant: The foliage is very attractive to us, but luckily is not so attractive to deer and rabbits. Brunnera are also rarely plagued by pests and diseases.
– Origin: Native to the woodlands of Eastern Europe and North West Asia.
