Edward F. Gilman2

Introduction

'Harbor Dwarf' nandina is a dense, compact cultivar of Nandina domestica (Fig. 1). It branches from the ground to form a dense mound about 18 inches in height. Dwarf nandina has smaller leaves and more branches than the species. Small, pink or bronze, tripinnately compound, leaves emerge in spring and turn orange to red in the winter. The flowers and fruits of this cultivar are also smaller than the species and less abundant.

Use and Management

'Harbor Dwarf' nandina is used in the landscape as an attractive and graceful ground cover or edging. Plant on 18- to 24-inch centers to form a thick ground cover. It is an interesting plant all year round.

Nandina domestica 'Harbor Dwarf' will grow well when given full sun or partial shade. It tolerates most well-drained soils and will endure periods of drought. The canes of this plant do not branch, but there are many stems originating at ground level to thicken the plant. 'Harbor Dwarf' nandina is commonly propagated by semi-hardwood cuttings in the fall. The largest advances in propagation are in tissue culture to produce virusfree plants.

Other dwarf cultivars include 'Compacta' - slower growing than the species with smaller leaflets, but eventually reaches 5 to 7 feet tall; 'Nana Purpurea' - to about 18 inches tall with coarse foliage turning bright, glossy red in winter; 'Woods Dwarf' - same as above, 18 inches tall best for the full sun.

Pests and Diseases

No pests or diseases are of major concern.
