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.

|Germination||A short period of cold and moist stratification (in the fridge) needed.|
1. Soak the seeds in clean water for 24 hours. Fully drain away all of the water and place the seeds in a zip-lock freezer bag. Place the seeds in the fridge. Make sure the seeds during this period not dry out or are waterlogged otherwise the pre-treatment will be ineffective.
2. After 6-8 weeks of the pretreatment seeds are ready to be sown.
3. Sow in a good quality potting compost. It shoudl be sterile and clean, never used before. Firm the compost gently, water and sow the seeds on the surface. Cover the seeds lightly (~2 mm) of vermiculite or sieved compost. Keep moist and at room temperature.
4. Germination will begin in a few weeks.
