Brunnera

Brunnera is a woodland plant that is easily grown in average, well-drained soil. Intolerant of dry soils, it prefers consistently moist, organically rich soil. In northern zones, morning sun is tolerable as long as the soil remains moist, and it needs to be grown in full shade with consistently moist soil in southern regions.

Zones 3-8.

Attributes: border plants, container, cut flower or foliage, mass planting. Deer resistant.

Once established little care is needed. Cut back the old foliage in the spring rather than in the fall; it will help to protect the crown during the winter. Winter mulch is also recommended. Though Brunnera tends to self-seed, the resulting seedlings are easy to pull out from unwanted areas or to replant elsewhere in the garden. It may also be propagated by division in the spring. 

PLANTING: Set plants 12 to 18 inches apart. Choose a location in partial shade, although full sun will be tolerated in cooler northern zones. In warmer southern zones, plants perform well even in dense shade. The soil should be deep and moisture-retentive, but welldrained.
MAINTENANCE: Water plants during periods of drought, otherwise once established little care is needed. Cut back the old foliage in the spring rather than in the fall; it will help to protect the crown during the winter. Winter mulch is also recommended. Though Brunnera tends to self-seed, the resulting seedlings are easy to pull out from unwanted areas or to replant elsewhere in the garden. It may also be propagated by division in the spring, every 2 or 3 years.
