Growing notes
- Plant in dappled to deep shade — silvered cultivars (‘Jack Frost’, ‘Looking Glass’) light up dark corners year-round
- Pure-blue spring flowers are an excellent companion to spring bulbs and pulmonarias
- Distinct from forget-me-not (Myosotis) — Brunnera leaves are much larger and the plant is reliably perennial
- Tolerates dry shade once established
