A compacta holly, or Ilex crenata 'Compacta', is a shrub that is sometimes referred to as a Japanese holly or a boxleaf holly. It is hardy in USDA Hardiness Zones 6a to 9b.
The compacta holly is a dense round shrub that is resistant to drought, heat, disease and wildlife. It has a moderate to slow growth rate and is used in landscaping for hedges, borders, topiary and entryways. This shrub prefers full to partial sun conditions and well-drained clay soil or loam. Compacta hollies have average to low water needs, and they do best when soil pH averages between 4.5 and 6.5.
