Ilex crenata (Japanese Holly)

Ilex crenata, commonly known as Japanese holly or box-leaved holly, is a dense, multi-branched, evergreen shrub with a rounded form that typically matures to 5-10’ tall and as wide. It is native to forests, thickets, and mountain slopes in Japan, Korea, China, and eastern Russia (Sakhalin). It is noted for its ovate to elliptic, crenate to serrulate, glossy, spineless, evergreen, deep green leaves (to 1 1/4" long) which are attractive all year, 4 petaled white flowers which bloom in 3-7 flowered cymes in late spring (May-June), and black rounded somewhat inconspicuous fruits (drupes to 1/4” diameter) which mature in fall on pollinated female plants.

• A full sun to part shade lover, this plant is easily grown in average, medium moisture, well-drained soils. This plant is not fussy and tolerates a wide variety of soils. However, it prefers moist, slightly acidic soil with good drainage. Some drought tolerance once established.
• Perfect for hedges and screens, foundation plantings, city gardens, or cottage gardens.
• Prune immediately after flowering.
• May be affected by aphids, scale insects, holly leaf miner, or holly leaf blight. Deer resistant.
• Propagate by seed or by semi-hardwood cuttings.
