Deciduous tree, a species of the genus Hazel (Corylus) of the Birch family (Betulaceae). Unlike most other types of hazel, this species is not a shrub, but a tree up to 20-30 meters tall, living up to 200 years with a thick-shirokopyramidal crown.

The root system is deep, rod-shaped. The tree-like hazel does not give root offspring. Annual shoots are yellowish-gray, with bristly-hairy pubescence. The bark on the trunk and old branches is gray, deeply fractured, separated by plates. The buds are oblong-ovate, with reddish-brown pubescent scales.

The leaves are rounded, dark green, broadly ovate or oval in shape, 7-12 cm long, 5-9 cm wide. Stipules are lanceolate, pointed. The base of the leaf blade is heart-shaped, it is narrowed to the top, short pointed, the leaf edge is double-toothed. Young leaves are pubescent from above, hairy from below mainly along the veins, later they become glabrous. Petioles 1.5-4.5 cm long, glandularly pubescent.

Blooms early in spring, in March-April. Male flowers are collected in cylindrical catkins 6-10 cm long, up to 6 mm thick. Female flowers are hidden in small buds, from under the scales of which only stigmas are exposed during flowering.

Bear nut fruits are single-seeded nuts, collected together in 3-8 pieces. The nut wrapper (pluska) is glandular, wide-open, its leaves are much longer than the nut itself and are repeatedly dissected into linear-lanceolate sharp segments, often sickle-shaped curved. The nuts are small, squeezed from the sides, with a very thick hard shell. Fruiting is not regular, productive years alternate with 2-3 lean ones. Harvest in August-September.

Although the fruits of the bear nut are small and with a very hard shell (it is impossible to crack it with teeth), their kernels are very tasty.

Instructions

1. Growing Himalayan Wild Hazelnut / Himalayan Hazel / Wild Hazelnut Tree (Corylus jacquemontii) from seed is a rewarding process. Follow these guidelines for best results.
2. Seed Preparation: Cold stratification is required. Place seeds in moist sand or vermiculite in a sealed bag and refrigerate at 1–5°C for 4–8 weeks before sowing. Some species may require 60–90 days of cold stratification for optimal germination.
3. Sowing: Sow seeds 0.5–1 cm deep in well-draining seed compost. Water gently and keep consistently moist but not waterlogged. Place in a bright location at 18–22°C.
4. Germination: Seeds typically germinate in 2–12 weeks after stratification. Germination may be sporadic — do not discard pots if no seedlings appear within the expected timeframe.
5. Transplanting: Transplant seedlings into individual pots once they have 2–3 pairs of true leaves. Harden off gradually over 7–10 days before planting in final position. Space according to the mature size of the species.
6. Aftercare: Water regularly during the first growing season. Apply a balanced fertilizer in spring. Mulch annually to retain moisture and suppress weeds. Prune as needed to maintain shape.
7. Hardiness: Hardy in most temperate climates. Suitable for USDA zones 4–8 depending on species. Established plants can tolerate winter temperatures well below freezing.
