Description

Gem Box® inkberry holly is a dense, ball-shaped plant with small dark green leaves. Foliage develops attractive red tips during the spring flush. Maintains good branching right to the ground so it never looks bare-legged like other cultivars can. As versatile and good-looking as boxwood with no disease issues!

Soil

Does best in moist (even very moist), slightly acidic soils.

Pruning

Naturally dense habit requires little pruning; may be trimmed after new growth has hardened off in late spring, though.

Uses

Hedges; edgings; foundation plantings; specimen; containers; mass planting.

Growing Tips

Tolerates shade well, but leaf color and overall foliage coverage is better with at least some sun. Grows most rapidly where moisture is consistently available.
