In the garden

Brunnera 'Langtrees' is a cultivated form of Brunnera macrophylla (family Boraginaceae) with the same woodland origins in the Caucasus. As a rhizomatous perennial it creates a low-covering habit that emerges each spring, producing sprays of blue flowers in April to May that rise above the foliage. Give it partial shade or full shade and a sheltered spot; an aspect facing north, east or west suits it. It prefers moist, well-drained soil and will do best in neutral to acidic conditions. Its UK hardiness rating is H5, meaning it is hardy across most of Britain but benefits from shelter from drying winds and exposed frost pockets. Use Brunnera 'Langtrees' as a ground cover beneath trees, at the front of a shaded border or in a woodland-style planting. Grouping several plants in drifts helps form an even carpet of foliage, with the blue spring flowers providing early-season interest when many shade plants are just emerging.
