Silver Korean Fir (Abies koreana ‘Horstmann’s Silberlocke’) features short, tightly packed evergreen needles with white undersides that curl upwards toward the stems. As it matures, this evergreen develops the classic pyramidal Christmas tree shape. It does best in full sun and prefers moist, well-drained soil. Silver Korean Fir can grow up to 30 ft. tall and is hardy in Zones 5 – 8.
