Horstmann's Siberlocke Korean Fir

Horstmann's Silberlocke Korean Fir (Abies koreana 'Horstmann's Silberlocke')

Horstmann's Silberlocke Korean Fir is a striking, slow-growing conifer with needles that curve upward to reveal bright silver undersides; the dense, conical habit and profuse violet-purple, upright cones provide year-round texture and seasonal show in cool-summer climates.

Distinctive Features

Curled, bi-color needles create a shimmering, frosted look in breeze and light, while abundant, showy cones appear even on young plants; the naturally tidy leader and layered branching read formal yet luminous.

Growing Conditions

• Sun Exposure: Full sun in cool climates; provide light afternoon shade in hotter regions.
• Soil: Moist, well-drained, acidic soil high in organic matter; avoid heavy, waterlogged sites.
• Water: Even moisture preferred; water deeply during establishment and extended dry spells.
• USDA Hardiness Zones: 5 to 7.
• Mature Size: Typically 10 to 20 ft tall and 6 to 10 ft wide in cultivation.
• Soil pH: Acidic to slightly acidic, about 5.0 to 6.5.

Ideal Uses

• Focal Point: Silver-backed needles and purple cones create an eye-catching specimen for front lawns and courtyards.
• Evergreen Structure: Dense, pyramidal form anchors mixed borders year-round.
• Color Contrast: Silvery sheen pairs beautifully with dark conifers and broadleaf evergreens.
• Small Collections: Compact growth suits conifer gardens and foundation plantings.

Low Maintenance Care

• Watering: Maintain consistent soil moisture, especially for the first 2 to 3 years; irrigate deeply in drought.
• Pruning: Minimal; preserve the central leader and remove only dead or rubbing branches in late winter.
• Fertilizing: Light spring feeding for acid-loving evergreens if growth is weak; avoid excess nitrogen.
• Mulching: Apply 2 to 3 in of shredded bark to conserve moisture, cool roots, and suppress weeds.
• Notes: Site with good air flow and drainage to limit root rot and adelgid issues; protect from reflected heat and drying winds.
