Abies nephrolepis (Manchurian Fir) is a species of fir native to northeastern China (Hebei, Heilongjiang, Jilin, Liaoning, Shaanxi), North Korea, South Korea, and southeastern Russia (Amur Oblast, Jewish Autonomous Oblast, Primorsky Krai, southern Khabarovsk Krai).
It is a medium-sized evergreen coniferous tree growing to 30 m tall with a trunk up to 1.2 m diameter and a narrow conic to columnar crown. The bark is grey-brown, smooth on young trees, becoming fissured on old trees. The leaves are flat needle-like, 10–30 mm long and 1.5–2 mm broad, green above, and with two dull greenish-white stomatal bands below; they are spirally arranged, but twisted at the base to lie flattened either side of and forwards across the top of the shoots. The cones are 4.5–7 cm (rarely to 9.5 cm) long and 2–3 cm broad, green or purplish ripening grey-brown, and often very resinous; the tips of the bract scales are slightly exserted between the seed scales. Each seed scale bears two winged seeds, released when the cones disintegrate at maturity in the autumn.
It is closely related to Abies sachalinensis, Abies koreana, Abies veitchii, and Abies sibirica, which replace it to the east, south, southeast, and west respectively. SOURCE: Wikipedia

Abies seeds need to be "overwintered" or stratified before they will germinate.
1. Soak overnight in warm water.
2. Then pre-chill (stratify) for 30 days. Seeds can be stratified in dampened peat, sand or moist vermiculite , in a plastic box or bag at 4°C or 5°C in a refrigerator. The seeds should not be frozen or in a wet medium.
Seed can be sown in early February in a greenhouse or outdoors in March. Normally will only germinate with light, but the stratification (described above) can help to increase the germination rate.
Sow Abies seeds 2-4 mm deep in the seed sowing mix.
Abies seeds will usually germinate in 21-40 days if overwintered and stratified or about 6 - 8 weeks if sown directly.
Soak seeds in cool water for two periods of 10 hours, but with a night break between them. Then after the second period, let the seeds drying out for a few hours. Next, put seeds into closed plastic bags but with little holes on the upper bag to allow gas exchanges. Place these bags in cold room/lower part of a refrigerator at +2° to +4°C. Check it out and stir it every 2 to 3 days to avoid mould development and watch also for the first appearing radicules. It usually takes 3 to 5 weeks to get about 10% of radicules to appear and then it's time for sowing.
