Himalayan Birch Betula utilis subsp. jacquemontii 'Inverleith'
ABOUT
The plant commonly known as the white-barked Himalayan birch 'Inverleith' is renowned for its striking appearance, primarily due to its distinctive bark. The bark is a brilliant, snowy white that peels off in sheets, showcasing a clean and bright surface that can be almost luminescent, especially in winter months when contrasted against darker surroundings. Its leaves are small to medium-sized, oval to ovate in shape with a pointed tip and a toothed margin. During the growing season, the foliage presents a lush, vibrant green color that is both fresh and lively. In autumn, the green leaves transition to a rich yellow, providing a striking, warm contrast to the paler bark. As a cultivar, 'Inverleith' often bears more compact and evenly arranged branches than other varieties. The branches arc gracefully, holding the leaves in a pattern that creates an attractive overall canopy structure. This dense, leafy canopy produces dappled shade beneath it during sunny days. On closer inspection of the branches, observers may find delicate catkins. These pendant structures add visual interest with their subtle texture and contrast beautifully against the foliage. Overall, the white-barked Himalayan birch 'Inverleith' is a plant of exceptional beauty. Its ghostly white bark and verdant leaves provide a visual appeal that can be appreciated in a variety of settings, from structured gardens to more natural landscapes.

WaterThe Himalayan Birch should be watered deeply once or twice a week, depending on weather conditions, to keep the soil consistently moist but not waterlogged. During hot and dry periods, increase the frequency of watering to prevent the soil from drying out completely. Generally, it's recommended to provide approximately 1 to 2 gallons of water per week for a young tree, adjusting for rainfall and adjusting as the tree matures and establishes. Overhead watering or using a soaker hose at the tree's base will ensure the water reaches the root zone efficiently.
LightThe Himalayan Birch thrives in full sun to partial shade conditions. For optimal health and growth, place it in a location where it can receive at least 6 hours of direct sunlight daily. It can tolerate some light shade, but too much shade may lead to sparse foliage and a less vigorous tree.
TemperatureThe Himalayan Birch can tolerate a wide range of temperatures but grows best in conditions where the average temperatures are between 60°F and 75°F. It can survive winter cold down to around -20°F and summer highs up to 85°F. Avoid planting in areas with extreme heat particularly where summer temperatures consistently exceed 85°F.
PruningFor the Himalayan Birch, prune to remove any dead, broken, or diseased branches, to improve the tree's structure, and to maintain its aesthetic shape. Pruning should be carried out during late fall to mid-winter when the tree is dormant to minimize sap bleeding. As a general rule, prune no more than 25% of the crown at a time, and focus on cutting back to a strong lateral branch or the tree's trunk.
CleaningAs needed
SoilHimalayan Birch requires well-draining soil with a mix of loam, sand, and organic matter. Aim for a slightly acidic to neutral pH of 6.0-7.5 for optimal growth.
RepottingHimalayan Birch trees grown in containers require repotting every few years to prevent root bounding and to replenish nutrients in the soil.
Humidity & MistingHimalayan Birch thrives in average outdoor humidity levels and does not require specific humidity adjustments.
Suitable locationsIndoor
Not ideal for indoor growth due to size and light needs.
Outdoor
Plant in well-draining soil, full sun to partial shade.

Life cycleThe life cycle of the Himalayan birch, specifically the 'Inverleith' cultivar, begins with seed germination, usually occurring in spring when soil temperatures increase. After germination, the seedlings establish and enter a juvenile phase, developing into young saplings with characteristic peeling white bark and serrated, downy leaves. As saplings mature into adult trees, they experience a period of vegetative growth, which may last several years, where the trees increase in both height and girth. During maturity, the Himalayan birch produces catkins, which are the reproductive structures, with male catkins releasing pollen and female catkins developing into small cones that disperse seeds. After successful pollination and seed set, the cycle continues as new seeds spread, potentially establishing new trees. The Himalayan birch may live for several decades, during which mature trees may go through multiple cycles of flowering and seed production.
PropogationPropogation time
Late winter to early spring
Propogation: The Himalayan birch, specifically Betula utilis subsp. jacquemontii 'Inverleith', is commonly propagated through seed sowing or semi-hardwood cuttings. However, the most popular method is through seed sowing, which is typically done in late fall or early winter. To propagate by seed, one would collect the seeds in autumn once they have matured and sow them superficially onto a well-drained, sandy compost mix. Seeds require exposure to cold temperatures for stratification, so outdoor sowing or refrigeration for several weeks can achieve this. Once the stratification period is complete, which usually lasts between 1 and 3 months, seeds can be moved to a warmer environment for germination. Care should be taken to keep the compost moist but not waterlogged, and once seedlings have reached a sufficient size, they can be potted on or planted out into their final position.
