Abies koreana
'Silberlocke '
Horstmanns Silberlocke Korean Fir
Origin: Discovered in 1978 in Scheneverdingen, Germany by L. G. Horstman and thus why it is often seen labeled as Horstman's Silberlocke.

Opinion
"
An unusual plant that is a welcome addition to the class garden, care should be taken to select a worthy form of the plant that is strongly pyramidal as I have seen and grown some unkempt forms. Interesting texture and colour.

Description and Growing Information
Flowering Period
| Cultivation |
| Requires well-drained slightly acidic to neutral soils. It may drop some needles in very cold situations and I have seen the one plant in the Cuddy Gardens drop almost all its needles but rebound to normal within a couple of growing seasons. A protected location from winter winds is strongly recommended. It is considered sensitive to urban pollution. |
| Shape |
| Loose, pyramidal form. |
| Growth |
| Slow |
| ID Characteristic |
| Strongly recurved needles, showing their silvery-whitish undersides. A slow-growing cultivar with an annual growth rate of 10 - 15 cm year, reaching 2 m in about 15 years. |
| Pests |
| None of note. |
| Habitat |
| Horticultural origin. |
| Leaf Description |
| 1 - 2 cm long, recurved needles displaying the silvery white underside. |
| Fruit Description |
| As pictured the cylindrical 5 cm cone is purple at maturity but pale green in infancy but often with an exudate of resin present. Cones are rare in infancy but common on mature specimens and as in most Abies species are held upright above the foliage. |
| Colour Description |
| Dark green above the needles but silver below, however when viewed in the form it is a mixture of the two. |
| Texture Description |
| A medium to coarsely textured plant with a somewhat unkempt form. |
| Notable Specimens |
| The A.M. Cuddy Gardens, Strathroy, Ontario, Canada. Whistling Gardens, Wilsonville, Ontario, Canada. |
| Propagation |
| Selected clones are grafted, however, it has the unusual characteristic of a high proportion of seedlings coming true to form since it does not hybridize freely with other species and cultivars of Abies. |
