About this cultivar:
Brunnera macrophylla 'Jack Frost' leaves are a distinctive silvery white with green primary and secondary veins and a thin green rim around the leaf edges. The basal foliage forms a hosta-like mound of heart-shaped leaves which remain attractive throughout the growing season. Smaller stem leaves are elliptic. However you buy it for the flowering longevity - tiny, forget-me-not-like flowers (light blue with yellow centers) rise above the foliage in an airy fashion on slender stems - the season is from February to June! A sport of Brunnera marcrophylla ‘Langtrees’. Species is synonymous with and sometimes sold as Anchusa myosotidiflora.

About this genus:
Brunnera is a genus of flowering plants in the family Boraginaceae. They are rhizomatous perennials, native to the woodlands of Eastern Europe and North West Asia where they thrive in cool, consistently moist locations. Numerous cultivars are available, most of which are used as groundcover in dappled shade. Some possess variegated foliage.
The genus gets its name from the Swiss botanist, Samuel Brunner, (1790-1844 ) who was a famous plant collector in the early 1800s who explored Crimea, the Caucasus, Siberia, Italy, and western Africa. Brunnera is known for its attractive, often hairy, heart-shaped leaves and clusters of small, blue or white, forget-me-not-like flowers. The genus brunnera contains just 3 species and unsurprisingly is very closely related to myosotis (Forget-me-not). The best known species to gardeners is macrophylla which in Latin means large-leaves (although you may know it as Siberian bugloss). Bugloss comes from Greek meaning ox tongue in probable reference to the roughness and shape of the leaves.
Brunnera grows best in part-shade or shade that is not too dry (not a problem here in Ballyrobert!). You can try it in full sun but it must have consistent moisture as the plants fade fast in very dry conditions. Soil wise we have not found Brunnera to be fussy at all.
Brunnera makes good groundcover and mass plantings in flower make many people ohh and ahh. Other plants that enjoy the same conditions as Brunnera, such as Dicentra, make grood partners. We also grow it with Geranium and Centaurea. You can also try it with Carex, Helleborus, or small ferns.
