Brunnera macrophylla

Bugloss
Boraginaceae
Perennials

These big-leafed woodland plants thrive in the rich organic soil under tall trees and shrubs. They grow in clumps to 1 1/2 ft. tall and 2 ft. wide; leaves are heart shaped, dark green. Airy clusters of tiny, yellow-centered, clear blue flowers look like related forget-me-nots (Myosotis). In shade, spring blooms keep coming into summer. Besides the green species, look for ‘Diane’s Gold’; ‘Langtrees’, with a necklace of white marks penciled around the inside of each leaf; ‘Jack Frost’, with silvery leaves veined and bordered in green; and ‘Looking Glass’, whose leaves are nearly white.

Brunnera works well with heucheras, hostas, and similar woodland plants, freely self-sowing once established. To increase germination, try freezing seeds before sowing. Needs well-drained, moisture-retentive soil. Increase by dividing clumps in fall.
