Ilex crenata 'Helleri' Helleri Holly1

Edward F. Gilman 2


Dwarf Japanese holly, (Ilex crenata) is one of the finest-textured shrubs available (Figure 1). These durable hollies are very flexible as landscape plants as they grow well in full sun to light shade. They lend themselves to a variety of soil types and are available at most nurseries and garden centers. The dark green foliage lends a rich air to any landscape, particularly when combined with lighter green turf and shrubs. Plant on 3- to 4-foot-centers to establish a row or mass planting.

Use and Management

The dwarf Japanese hollies are best used in mass groups as low shrubs, low hedges, or tall groundcovers. The compact habit of growth, slow growth rate, and small leaves make these ideal plants for use as clipped, formal hedges. Adjacent plants will often grow together looking like a row or group of green mounds. Eventually, the crowns grow completely together forming a sea of green.

Cultivars: 'Convexa' grows to about eight feet in a vase or rounded form and has cupped, glossy leaves; 'Compacta' has a compact growth habit and grows to about five feet tall; 'Helleri' has a slight grayish cast to the foliage which sets it apart from other Japanese hollies; 'Northern Beauty'—improved cold tolerance, reaches a height and spread of three feet; 'Rotundifolia'—dense habit, large size, to 12 feet.

Propagation is by cuttings.

Pests and Diseases

Pest problems are many, including scale, spider mites, spittle bugs, and nematodes, but these are often of minor consequence.

No diseases are of major concern.
