Brunnera macrophylla ‘Dawson’s White’, commonly known as variegated Siberian bugloss, is a perennial plant that offers exceptional beauty and versatility for gardeners. Known for its striking foliage and delicate blue flowers, this cultivar is a standout addition to shaded and woodland gardens.
Characteristics of Brunnera macrophylla ‘Dawson’s White’
Foliage: The most notable feature of ‘Dawson’s White’ is its large, heart-shaped leaves with bold, creamy-white edges. The variegation creates a striking contrast against the deep green centers, making the plant a focal point in any garden setting.
Flowers: In early spring, ‘Dawson’s White’ produces clusters of small, sky-blue flowers that resemble forget-me-nots. These delicate blooms add a charming splash of color that complements the variegated foliage.
Growth Habit: This Brunnera cultivar forms a dense, clump-forming habit, typically reaching 12-18 inches in height and spreading about 18-24 inches wide. Its compact size makes it suitable for various garden spaces, including borders, ground covers, and container plantings.
Ideal Growing Conditions
Light: ‘Dawson’s White’ thrives in partial to full shade. It is an excellent choice for brightening up shaded areas where other plants might struggle. While it can tolerate some morning sun, too much direct sunlight can scorch the leaves.
Soil: This plant prefers moist, well-draining soil rich in organic matter. Consistent moisture is essential, especially during hot, dry periods. Adding compost or leaf mold to the soil can improve its texture and fertility.
Watering: Regular watering is crucial, particularly during dry spells. The soil should be kept consistently moist but not waterlogged. Mulching around the base of the plant helps retain moisture and keep the roots cool.
Temperature and Hardiness: Brunnera macrophylla ‘Dawson’s White’ is hardy in USDA zones 3-8, making it suitable for a wide range of climates. It can withstand cold winters and will die back to the ground, re-emerging in spring.
Planting and Maintenance
Planting: When planting ‘Dawson’s White’, space the plants about 18 inches apart to allow for their mature spread. Dig a hole slightly larger than the root ball, place the plant at the same depth it was growing in its container, and backfill with soil. Water thoroughly after planting.
Maintenance: This Brunnera cultivar requires minimal maintenance once established. Regular watering and occasional feeding with a balanced fertilizer will promote healthy growth. Deadheading spent flowers can encourage a tidier appearance, although it is not necessary for continued blooming.
Division: To maintain vigor and manage size, divide the plants every 3-4 years in early spring or fall. Dig up the clump, gently separate the roots, and replant the divisions.
Pest and Disease Control: ‘Dawson’s White’ is generally pest and disease-resistant. However, slugs and snails may occasionally feed on the foliage. Use organic slug pellets or copper barriers to protect the plants.
Garden Uses
Shade Gardens: ‘Dawson’s White’ is ideal for adding color and interest to shaded garden areas. Its bright foliage illuminates dark corners and creates a stunning contrast with other shade-loving plants.
Woodland Gardens: The plant’s natural habitat is similar to woodland conditions, making it a perfect choice for woodland garden designs. Pair it with ferns, hostas, and other shade-tolerant perennials for a lush, layered effect.
Ground Cover: Due to its dense growth habit, ‘Dawson’s White’ works well as a ground cover. It can help suppress weeds and fill in bare spots under trees and shrubs.
Containers: Its compact size and attractive foliage make it an excellent candidate for container gardening. Use it in combination with other shade-loving plants to create beautiful patio displays.
