Inkberry Holly ‘Shamrock’ | Plant Profile
Inkberry Holly ‘Shamrock’ (Ilex glabra) are upright shrubs native to the eastern coasts of the United States. The dark green leaves are oval and glossy, and serrated at the tip. Ornamentally insignificant green/white flowers bloom in spring. If pollinated, long lived black berries appear in the flowers. The ‘Shamrock’ variety smaller and rounder than most in this species.
‘Shamrock’ prefer average fertility soils in full sun to part shade. These coastal shrubs are able to tolerate wet soils and are not attractive to rabbits and deer.
‘Shamrock’ are versatile shrubs with a wide array of applications. They can be planted singularly, massed in a group, or aligned to create a hedge. They are ideal options near streams, ponds, or to help absorb wet spots.
Inkberry Holly ‘Shamrock’ are medium sized shrubs, growing up to 4′. The green and glossy leaves may remain evergreen if temperatures do not plummet below zero often. Some pruning may be required to remove dead branches. To maintain as a hedge, more pruning is required.
Serious diseases or pests are uncommon. Leaf spot and spider mites may appear in dry conditions. Soils should be of low pH to maintain the vibrant green leaves.
Birds are particularly attracted to the berries that grow on pollinated female plants. These are wonderful options for pollinator gardens, as honey made from Inkberry blooms is highly coveted.
