Ilex x meserveae 'Castle Spire'

Castle Spire Holly

Ilex × meserveae ‘Castle Spire’ is an evergreen holly valued for its narrow upright habit, glossy blue-green foliage, and abundant bright red berries on female plants when pollinated. The leaves are moderately spined and retain rich color through winter, while the naturally narrow form makes it especially useful where vertical evergreen structure is needed in limited space.

Type: Evergreen shrub
Mature Size: Width: 3–4 ft · Height: 8–10 ft
USDA Zones: 5a–7b

Form: Narrow, upright, pyramidal

Light: Full sun to part shade

Soil: Moist, well-drained, slightly acidic soil

Wildlife: Berries attract birds

Features & Landscape Uses:
Excellent for narrow hedges, entry accents, foundation corners, and vertical evergreen structure where winter berry display is desired. Its narrow habit fits tight planting spaces well.

Care:
Plant in well-drained acidic soil and protect from drying winter winds in exposed sites. Prune lightly in late winter or early spring if shaping is needed. A male pollinator such as Castle Wall® improves berry production.
