Ilex crenata ‘Sky Pencil’, commonly known as Sky Pencil Holly, is a unique, columnar evergreen shrub admired for its narrow, upright habit and glossy, dark green foliage. Reaching 6 to 10 feet tall and just 1 to 2 feet wide, this non-native Japanese holly is perfect for tight spaces, vertical accents, and container plantings. It requires little pruning to maintain its sculptural form, making it a favorite for formal, urban, and modern garden designs. However, as a non-native species, it offers minimal habitat or food value for native wildlife.

Why choose Sky Pencil Holly:

• Slender silhouette: Naturally narrow and upright, ideal for small-space vertical accents

• Evergreen structure: Glossy dark green leaves provide year-round interest

• Low-maintenance: Holds its shape with little to no pruning

Cultivating tips:

• Sun exposure: Best in full sun to part shade

• Soil needs: Prefers moist, well-drained, slightly acidic soil

• Maintenance: Minimal pruning required; protect from heavy snow and ice accumulation

Designs for your garden:

• Vertical accents: Use at entrances, corners, or in rows to add height and structure

• Foundation plantings: Adds elegance and evergreen texture in narrow spaces

• Containers: Excellent for flanking walkways, patios, or formal beds

Ecological considerations:

• Non-native species: Provides little food or shelter for birds, insects, or pollinators

• Not a host plant: Does not support native caterpillars or specialist insects

• Combine with natives: Pair with native evergreens and perennials to support biodiversity
