Ilex glabra Inkberry, Gallberry1

Edward F. Gilman2


This upright, clump-forming, evergreen shrub is valued for its foliage and fruits. The lustrous, dark green leaves may have a few obtuse teeth toward the leaf apex or they may have entire margins. They are obovate to oblanceolate in shape and may reach a length of 3/4 to 2 inches. Gallberry becomes somewhat open with age and often loses its small lower branches. Female plants have berry-like, black drupes that occur from September to May of the following year. These 6- to 8-foot-tall plants are especially valuable to birds for their persistent fruits and branch structures. The flowers of Ilex glabra appear in May, and the staminate and pistillate flowers occur on separate plants. The female flowers are solitary, and the male flowers are borne on a stalk consisting of 3 or more flowers. Both sexes of flowers have creamy white petals and are inconspicuous.

Use and Management

Gallberry is excellent when used in mass plantings and as naturalizing material. It has been utilized as a hedge, foundation plant and accent plant. It makes a poor hedge because it thins toward the bottom.

Ilex glabra prefers a full sun to partial shade location in the landscape and moist, acidic soils; high-pH soils should be avoided. Older plants may be renewed by heavy pruning.

Cultivars include 'Compacta', dwarf female clone, tighter branching and foliage than species, grows 4 to 6 feet high, becomes leggy at base; 'Georgia Wine', turns burgundy during the winter; 'Ivory Queen' and 'Leucocarpa', white fruited forms, grow 6 to 8 feet high; 'Nigra', purplish foliage in winter; 'Nordic', compact rounded form, grows 3 to 4 feet tall, cold hardy, needs pruning to keep it dense; 'Shamrock', compact form, slower growing then species, leaves smaller and flat; 'Steed', compact form; 'Squat', compact form.

Propagate the gallberry by seed, layering, cuttings, and grafting.
