Read 'Plant Profile: Korean Fir (Abies koreana)' at http://www.KarensGardenTips.com.

A cool weather evergreen tree, this native of South Korea is ideal for a small garden. It grows in temperate forests with high rain and snow fall and high humidity in summer. Its glossy dark green needles are 1-1½ inch long and have two silver-white lines on the underside. Insignificant deep red male strobili and purple to pink female strobili are borne on the same tree and are followed by purple-blue cones up 2-3.5 inches long. The cones are upright, cylindrical and have clear resin wax-like drippings down the sides. They turn rich dark brown as they mature and disintegrate. Trees need protection from strong winds and air pollution.
