Ilex glabra Strongbox® (Inkberry) is an evergreen, stoloniferous shrub of compact, rounded habit with a lush foliage of thick, spineless, blue-green leaves. In spring, it produces inconspicuous small greenish-white flowers. Resembling boxwood, it is a good substitute as it is resistant to disease, pests, and winter burn. Highly adaptable, its modest size makes it ideal for small gardens or containers.

  • Slow growing, this evergreen shrub grows up to 2-3 ft. tall and wide (60-90 cm). Remove root suckers regularly if colonial spread is not desired.
  • A full sun to part shade lover, this plant is best grown in average, medium to wet, well-drained, acidic soils. Tolerates poorly drained soils as well as wet boggy conditions. Does poorly in neutral to alkaline soils and often dies.
  • Generally pest and disease free. Deer and rabbit resistant.
  • Mass in mixed shrub borders. Perfect for hedges, edging or for foundation plantings. Excellent shrub for wet soils and along streams or ponds.
  • Prune to shape in early spring just before new growth begins.
  • Native to North America.
