Silver Birch

$5.50/200 Seeds

The Silver Birch (Betula pendula) is an elegant, deciduous tree known for its striking white, papery bark that peels in thin layers, graceful weeping branches, and small, bright green triangular leaves that turn a vibrant golden-yellow in autumn. It’s a fast-growing, hardy tree, often with a central trunk and delicate, drooping twigs, creating a light, airy canopy that offers year-round interest with its contrasting white trunk against green foliage and autumn gold.

Key Characteristics:
Bark: Smooth and silvery-white, becoming more fissured and blackish at the base with age; it peels horizontally.
Leaves: Small, light green, and roughly triangular with serrated edges, providing dappled shade.
Form: Pyramidal to narrowly ovate, with slender, often pendulous (weeping) branch tips.
Flowers: Pale green catkins appear in spring.
Fruit: Small, winged nutlets in pendulous cones (strobilus) that fall in autumn.
Size: Medium-sized, typically reaching 10-20 meters in height.
Seasonal Appeal:
Spring/Summer: Lacy, light green foliage provides shade.
Autumn: Leaves turn brilliant yellow.
Winter: Striking white trunk and red-tinged branches stand out against the sky.
Habitat & Growth:
Prefers full sun to partial shade and well-drained soil but is adaptable.
Tolerates frost, snow, and mild drought once established.
A pioneer species, often one of the first trees to grow in new areas.

Growing Instructions
To grow silver birch from seed, collect tiny winged seeds, then stratify (cold-treat) them in a fridge for 6-12 weeks to mimic winter, mimicking the natural chilling they need. Sow them shallowly in moist seed mix, cover lightly with grit or soil, keep consistently moist and in light, and expect germination in weeks, transplanting the strong seedlings carefully to avoid root damage as they grow. 2. Stratify (Cold-Treat) Seeds Place seeds in a plastic bag with a little moist (not wet) seed-raising mix or sand. Store in the refrigerator (not freezer) for 6 to 12 weeks to break dormancy. Check weekly to ensure the medium stays damp. 3. Sow the Seeds When: Spring, after stratification. Mix: Use a fine seed-raising mix, possibly with some sand or grit. Sowing: Sprinkle seeds on the surface and cover very lightly (1-2mm) with soil or grit; don't bury them deeply. Water: Gently mist with water. 4. Germinate & Grow Location: Keep in a light spot away from direct sun, ideal temperature 18-20°C (65-68°F). Moisture: Keep soil consistently moist; these tiny seeds dry out quickly. Emergence: Seedlings should appear in 2-6 weeks. Transplant: When seedlings are strong (handle by the leaf!), carefully transplant them to individual pots to prevent root tangles. 5. Care for Seedlings Acclimatize gradually to sunnier spots. Keep well-watered and provide temporary support if needed. Feed regularly with liquid fertilizer until August to encourage growth.
