WaterFor Siberian Bugloss or Brunnera macrophylla 'Dawson's White', it is essential to maintain consistent moisture without overwatering. Water the plant deeply once a week, providing about one to one and a half gallons per plant, depending on the climate and soil conditions. During hot or dry spells, increase watering frequency to ensure the soil remains moist but not soggy. Cut back on watering during the fall and winter when the plant's growth slows down. Always check the top inch of soil for dryness before watering to prevent overwatering which can lead to root rot.
LightSiberian Bugloss thrives best in partial shade to full shade conditions. It should be planted in a location that receives morning sunlight but is protected from the harsh afternoon sun, as too much direct sunlight can scorch the leaves. Ideally, a spot under a canopy of trees that offers dappled sunlight or light shade throughout the day is perfect for this perennial.
TemperatureSiberian Bugloss prefers a cool to moderate temperature range, thriving best between 50°F and 75°F. While the plant can tolerate temperatures down to 20°F, it could be damaged by frost and extremely cold conditions. It's not suitable for extreme heat, and temperatures consistently above 80°F may stress the plant. In zones with hotter climates, it's especially important to provide adequate shade to keep the plant cool.
PruningPruning Siberian Bugloss involves removing dead or damaged leaves to maintain plant health and aesthetics; this can be done as needed throughout the growing season. The best time for more extensive pruning is in late winter or early spring before new growth starts. Cut back any old foliage to encourage fresh growth and maintain the plant's compact shape.
CleaningAs needed
SoilSiberian bugloss 'Dawson's White' prefers a soil mix rich in organic matter with good drainage and a pH range of 5.5 to 7.5. A blend of garden soil, compost, and a small amount of perlite or coarse sand can create an ideal growing medium.
RepottingSiberian bugloss 'Dawson's White' doesn't require frequent repotting and can typically be repotted every 2 to 3 years or when it outgrows its current container.
Humidity & MistingSiberian bugloss 'Dawson's White' thrives best in moderate humidity levels but is adaptable to varying household humidity conditions as long as the soil moisture levels are appropriate.

Life cycleThe life cycle of Brunnera macrophylla 'Dawson's White', also known as Siberian bugloss, begins with germination from seed, typically occurring when temperatures warm in spring. The seedling stage follows, with the plant developing its first true leaves and establishing a root system. It then enters into a vegetative growth phase where it forms a clump of heart-shaped, variegated leaves and gains size and strength. During its reproductive stage, which often occurs in the spring, Siberian bugloss produces small, forget-me-not-like blue flowers on airy sprays above the foliage. Once pollinated, the flowers will set seed which can then be dispersed to create new plants. After flowering, the plant will enter a period of senescence, particularly if it is a perennial variant, where it will die back in the winter and go dormant until the next growing season begins.
PropogationPropogation time
Spring to Summer
Propogation: Brunnera macrophylla 'Dawson's White', commonly known as Siberian bugloss, can be propagated effectively through division, which is the most popular and easiest method. This is usually done in the spring when the plant has begun to grow actively. To propagate by division, you'll need to carefully dig up an established clump and gently separate it into smaller sections, ensuring that each section has a portion of the root system intact. It's important to replant the divisions immediately, watering them in well after planting. Each division should be spaced about 12 inches (approximately 30 centimeters) apart to give them ample room to grow. This method allows gardeners to create new plants that are genetically identical to the parent plant, maintaining the variegation that 'Dawson's White' is known for.
