Inkberry Holly Profile for Maryland

A Coastal Plain profile of inkberry holly covering evergreen size, light, moisture, salt and flood notes, and slow suckering.

Inkberry holly (Ilex glabra) is an evergreen shrub that University of Maryland Extension identifies as native to Maryland’s Coastal Plain. The profile supports a site screen, not a statewide range claim; verify that the species and nursery material are appropriate for the planting location.

Site profile

Field Source description
Mature size About 5–8 feet tall.
Light Full sun to full shade.
Soil All textures; dry to periodically wet; acidic pH 4.5–6.
Water and salt Tolerates periodic flooding, drought, and salt. The source gives no salt threshold or flooding duration.
Growth and form Slowly suckers. Older plants may become bare near the base; UMD recommends selective thinning rather than shearing.
Fruit Female plants may produce berries after pollination; the source does not give a firm pollinator-placement rule.

Inkberry holly’s source-listed height is 5–8 feet; it is evergreen and slowly suckers. It fits full sun to full shade, dry to periodically wet acidic soil, and qualitative periodic-flooding, drought, and salt conditions without stated thresholds. Older shrubs may thin near the base; selective thinning is recommended over shearing.

The graphic summarizes the UMD site and maintenance notes; it is not a pruning cut guide, and the stress tolerances are not thresholds.

Inkberry’s broad light and moisture descriptions still require a check of drainage, acidity, and actual flood duration. Its salt note is qualitative and does not establish tolerance of a particular road’s runoff or spray. Allow for slow suckering and consider how the shrub will look if its lower stems thin with age.
