Brunnera m. 'Jack Frost'

Soil: Evenly moist, humus rich soil.
Light: Grows well in morning sun to full shade, in all but the driest of spots. In hot afternoon sun, it will need moist soil or the leaves will burn, but in the shade occasional water is sufficient.
Water: Moderate, prefers even moisture.
Spacing: 24" apart.
Fertilizing: 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. In successive years, if soil is poorer in quality, and light scattering of slow release fertilizer in spring should be sufficient.
Winterizing: Keep old foliage over winter to protect crowns. After the ground freezes, apply a loose layer of oak leaves, pine boughs, or straw. You can gradually remove mulch, and cut back old foliage in early spring.
Maintenance & pruning: When the clump starts to deteriorate in the center, it is time to divide it. Plants may be divided easily in early autumn. Plant crowns at soil level. Sometimes self seeds generously, but usually the seedlings have plain green leaves. Remove any green foliage that appears on variegated forms.
