Inkberry Holly

About this plant

Ilex glabra 'Shamrock' is a superior cultivar of Inkberry Holly, celebrated for its exceptionally dense, compact growth habit and refined appearance. Unlike some inkberry varieties, 'Shamrock' maintains a neat, rounded shape without becoming leggy, making it an excellent choice for formal plantings or low hedges. Its small, dark green leaves provide year-round interest and a soft texture that complements a wide range of garden styles. From tiny white flowers in late spring emerge small, persistent black berries that add subtle winter appeal, especially when contrasting against a snowy backdrop. These berries are also a valuable food source for various bird species, bringing life and activity to your garden during the colder months. Hardy and adaptable, 'Shamrock' Inkberry thrives in a range of conditions and is particularly well-suited for moisture-retentive areas, including rain gardens or alongside water features. Its evergreen nature ensures continuous visual appeal, making it a foundation plant or an excellent substitute for boxwood in areas prone to boxwood blight.

Care & maintenance

Requires minimal pruning to maintain shape; prune in late winter or early spring before new growth appears. Tolerant of both wet and dry conditions once established, but prefers consistently moist, well-drained, acidic soil. Mulch annually to help retain soil moisture and regulate temperature.
