Ilex crenata 'Dark Green'

Commonly known as Japanese holly or box-leaved holly, Ilex crenata is a slow-growing, evergreen shrub often chosen as a more robust alternative to box (Buxus sempervirens), as it's not affected by box blight or box moth, and is more tolerant of low temperatures. It's perfect for growing as a green foil behind more colourful plants, clips nicely into a ball, and works well in pots.

Ilex crenata 'Dark Green' has deep-green, convex leaves that closely resemble those of true box leaves more than other varieties.

Grow Ilex crenata 'Dark Green' in full sun or partial shade in moist, well-drained soil. For best results grow in acidic soil, but neutral to alkaline soils are also tolerated. Prune hedges or topiary in late summer – plants growing as freestanding shrubs need little pruning. Mulch annually in autumn with home-made compost or well-rotted manure.
