Ilex glabra 'Shamrock' (inkberry)

University of Maryland Extension Recommended Native Shrub

Maryland DNR Deer-Resistant Plant

'Shamrock' is an inkberry cultivar known for its compacted rounded shape and fewer suckers than other cultivars. It typically matures to 3-4’ tall, and can spread by root suckers to form colonies. Female flowers produce pea-sized, jet black, berry-like drupes. Inkberry honey is prized for its flavor. Tolerates rabbits, excellent for shrub borders. 'Shamrock' is a compact rounded cultivar and suckers less than other cultivars. Since male cultivars are not readily available, choose a straight species inkberry to have a chance of obtaining a male that can pollinate the female. All Ilex species are somewhat toxic if ingested; sensitivity varies. 

Inkberry is native to the coastal plain of eastern North America. It is most commonly found in sandy woods and the peripheries of swamps and bogs. Inkberry attracts honey bees and birds. Evergreen foliage provides protection for birds.
