Siberian Bugloss
Basic Information
Common Name: Siberian Bugloss
Scientific Name: Brunnera macrophylla
Native Habitat: Woodlands of the Caucasus
History / Discovery / Cultivator
Brunnera macrophylla, commonly known as Siberian Bugloss, Heartleaf Brunnera, or False Forget-Me-Not, boasts a captivating history rooted in the woodlands of the Caucasus region, encompassing areas of Georgia, Russia, and Turkey. The plant’s journey from its native habitat to gardens worldwide reflects a tale of botanical discovery and horticultural enthusiasm.
The genus Brunnera is named in honor of Samuel Brunner, a Swiss botanist and naturalist. The species name, macrophylla, translates to “large-leaved,” a characteristic feature that distinguishes this plant. While the exact date of its initial discovery remains somewhat obscure in readily accessible historical records, its presence in botanical literature and subsequent introduction to cultivation suggest a timeline spanning the 19th century.
Early botanical expeditions to the Caucasus mountains, a region renowned for its diverse flora, likely encountered and documented Brunnera macrophylla. These expeditions played a crucial role in bringing new plant species to the attention of European botanists and horticulturalists. As seeds and specimens were collected and transported back to Europe, interest in cultivating this unique plant began to grow.
The plant’s appeal lies in its attractive foliage – large, heart-shaped leaves that form a dense groundcover. Its delicate, forget-me-not-like blue flowers, which bloom in spring, further enhance its ornamental value. These qualities quickly made it a desirable addition to gardens, particularly in shaded areas where it thrives.
Several cultivars of Brunnera macrophylla have been developed over the years, each showcasing variations in leaf color and pattern. These cultivars have contributed significantly to the plant’s popularity and widespread cultivation. One notable example is ‘Jack Frost,’ known for its silver-veined leaves, which was introduced by Walters Gardens, Inc. This cultivar, along with others such as ‘Looking Glass’ (also known for its striking silver foliage) and ‘Alexander’s Great’ (a larger, more robust variety), demonstrate the plant’s potential for horticultural improvement and the ongoing efforts to enhance its aesthetic qualities.
The popularity of Brunnera macrophylla can also be attributed to its relatively easy cultivation and adaptability. It is a hardy plant that can tolerate a range of conditions, although it prefers moist, well-drained soil and partial shade. Its ability to form a dense groundcover makes it an excellent choice for suppressing weeds and adding visual interest to shady garden areas.
Furthermore, the plant’s appeal has been amplified by its inclusion in numerous gardening publications and online resources. These platforms have played a vital role in disseminating information about its cultivation, care requirements, and ornamental uses, thereby promoting its adoption among both amateur and experienced gardeners.
In summary, Brunnera macrophylla‘s journey from its native Caucasus habitat to gardens worldwide is a testament to the enduring appeal of botanical discovery and horticultural innovation. Its attractive foliage, delicate flowers, and ease of cultivation have cemented its place as a beloved ornamental plant, while the ongoing development of new cultivars ensures its continued popularity in the years to come.

Botanical Insights
Adaptations
Siberian Bugloss exhibits several interesting adaptations that contribute to its survival. Its large, heart-shaped leaves are well-suited for capturing ample sunlight in the shaded woodland environments where it naturally occurs. The broad leaf surface area maximizes photosynthesis, allowing the plant to thrive in lower light conditions. Furthermore, the plant’s rhizomatous root system enables it to spread and form dense colonies, effectively competing with other plants for resources. This groundcover habit also helps to suppress weed growth. Finally, the forget-me-not-like flowers, which are typically blue, attract pollinators to ensure successful reproduction.
Propagation Methods
Several methods can be used to propagate Siberian Bugloss. Division is the most common and straightforward approach. In early spring or fall, carefully dig up a mature plant and divide the rhizomes into smaller sections, each with its own roots and shoots. Replant these divisions in well-prepared soil. Seed propagation is also possible, although it can be slower. Seeds should be sown in a cold frame in the fall or stratified (cold-treated) for several weeks before sowing in the spring. Root cuttings can also be used, though this method is less common.
Toxicology
While Siberian Bugloss is generally considered non-toxic, ingestion can cause mild irritation, particularly in sensitive individuals. The plant contains compounds that can cause oral irritation if chewed or swallowed. Symptoms may include a burning sensation in the mouth, mild stomach upset, or skin irritation upon contact with the sap. Although serious reactions are rare, it is advisable to keep the plant out of reach of young children and pets. If ingestion occurs, rinse the mouth with water and seek medical advice if symptoms persist. For pets, contact a veterinarian if any unusual symptoms are observed after ingestion.
Common Problems
Pests:
- Slugs and Snails
- Aphids
- Spider Mites
Diseases:
- Powdery Mildew
- Leaf Spot
- Root Rot (in poorly drained soil)
Other:
- Leaf Scorch (caused by too much sun or dry soil)
- Yellowing Leaves (caused by nutrient deficiency or overwatering)
- Slow Growth (caused by poor soil or inadequate light)
Rarity & Value
Rarity:
While Siberian Bugloss is not generally considered rare, specific cultivars with unique variegation patterns or improved characteristics may be more difficult to find and therefore more valuable. Additionally, certain cultivars may be less readily available in some regions, contributing to their perceived rarity. The “rarity” of a specific cultivar will often fluctuate based on collector interest and breeder propagation levels.
Value:
The value of Siberian Bugloss typically depends on several factors, including the cultivar, size, health, and overall appearance of the plant. Larger, more established plants with well-developed foliage are generally more valuable. Cultivars with striking variegation or unique flower colors may also command higher prices. Market trends and collector demand also play a role in determining value. Finally, the source of the plant and its provenance (e.g., a reputable nursery or a known collector) can also influence its perceived value.
