Perennial. Zone 2. Boraginaceae. Syn. Anchusa myosotidiflora. A.k.a. SIBERIAN BUGLOSS. Caucasus Mountains; Asia Minor. The odd common name “Bugloss” is derived from the Greek words for “ox’s tongue” – bous = head of a cow, and gloss = tongue – in reference to the shape and texture of the leaves. The Siberian moniker is a bit inaccurate, as there is another, very similar, but much rarer species, Brunnera sibirica, which no doubt better deserves the title. The genus is named after Samuel Brunner (1790-1844), a Swiss botanist. Macrophylla = “large leaves”, again in reference to the substantial basal foliage.
I am very fond of this attractive spring bloomer, though I must admit that I once killed a newly transplanted colony through neglect one hot, busy summer, from lack of water. It’s definitely a shade/good soil/plenty of moisture sort of thing in our Cariboo-Chilcotin climate, and it is very happy in the high shade of trees, or even at the north side of the house, far enough out from the wall so it can catch a few sun rays for part of the day.
Handsome, heart-shaped, rough-textured, deep green foliage in big clumps to 18 inches tall produce many clusters of tiny, true blue, yellow-eyed, forget-me-not-like flowers from mid-spring into summer.

Brunnera macrophylla received much attention in 1802 from European botanists and gardeners when it was collected during an exploratory expedition to the Caucasus Mountains led by Count Apollos Apollosovich Mussin-Pushkin, a dedicated scientist with interests in both mineralogy and botany. Others had apparently noticed the plant’s horticultural possibilities before the roving Russian Count brought it home, as the plant was first documented in English gardens almost a century earlier, in 1713.
I think it’s a rather wonderful plant, and so did the noted American gardener and writer Louise Beebe Wilder, for in her charming and informative 1935 book, What Happens in My Garden, she had this to say in the chapter titled “True Blues Among the Early Blossoms”:
Anchusa myosotidiflora, like a giant dark blue Forget-me-not and blooming before it, is invaluable. It grows well in sun or shade, but likes a soil that is not too dry. It has a thousand uses in the garden. It wreathes the yellow skirts of the Forsythias with lovely effect, is lovely in low borders with early Trollius, Doronicum, and blue and white Camassias, is lovely as an interplanting for Tulips of almost any colour. Try it with some of the “difficult” bronzes, as well as those of purer hue…The Anchusa enjoys a long season. It is, I believe, now properly known as Brunnera macrophylla.
Stylish silvery-white-variegated cultivars of this old-fashioned plant are supremely popular right now, but the good old green-leaved sort sets off the pretty flowers without distraction, and I think I may still like it best.

Once the flowers finally subside in early summer, the plants can start to look a little bit tired, but can be refreshed by some judicious pruning, and perhaps some compost or well-rotted manure gently scratched into the soil at the base of the foliage crowns. Don’t forget to water this in well, and keep an eye on soil moisture levels, especially through the heat of July and August.
Brunnera macrophylla is shallow rooted, and is anchored in the ground by long, brittle rhizomes. It spreads to form a substantial colony where happy, but is very easily curbed by pulling back encroaching roots. It divides well in early spring, though divisions may take a season to re-establish.
Sun to shade, good soil and moisture.
