Growing Brunnera (Siberian Bugloss; Heartleaf Bugloss)

Latin Name Pronunciation: brun'er-ruh   

Brunnera generally thrive in cool shady woodland situations with moist soil rich in organic matter; they do not tolerate dry soil or hot humid summers. Heart-shaped, softly hairy leaves beautifully set off sprays of sparkling blue Forget-me-not flowers in spring. This shade lover makes a well-behaved but effective ground cover in evenly moist, well-drained soil. Brunnera is most at home in woodlands or along a shady streambed, where it will form a lush under story of quiet beauty.

Light/Watering: Prefers partial shade or shade; tolerates dry shade but needs moisture in sunny conditions. Variegated forms require moist soil and will scorch in sun. Leaves will turn brown and crisp with too much sun or too little water but if cut back and watered well plants often recover.

Fertilizer/Soil and pH: Grow in well-drained soil that is moderately fertile and humus-rich. We do not recommend fertilizing at planting time or during the first growing season.

Pests/Diseases: Tough and relatively trouble-free.

Companions: Daffodils and other woodland plants.

Dividing/Transplanting: Divide in spring; plant crown at soil level.

End-of-Season Care: Keep old foliage over winter to protect crowns. After the ground freezes, apply a loose layer of oak leaves, pine boughs, or straw.

 

Calendar of Care

Early Spring: Gradually remove winter cover. Cut back old foliage; large clumps may be divided.

Summer: Remove any green foliage that appears on variegated forms.
