Pittosporum tobira 'Variegata' Variegated Pittosporum1

Edward F. Gilman2

Introduction

Glossy, creamy white and green variegated leaves, easy care, and an open, round canopy make pittosporum a popular landscape shrub (Fig. 1). However, rapid growth when young makes this a fairly high maintenance shrub, requiring frequent pruning. Growth does slow with age as the plant reaches about 10 feet tall. Clusters of creamy white flowers with a fragrance similar to orange blossoms appear in spring, but they are rarely seen on shrubs because they are frequently pruned off with the regular trimming required to keep the plant in check. Flowers also get lost in the green and white foliage. It is really better suited as a small tree with lower branches removed to reveal the multi-stemmed trunk, and branches should be left unpruned to allow the flowers to show in the spring. Prune after the flower display. Careful training and pruning can create an ornamental small tree form.

Use and Management

Excellent when used as a specimen or informal shrubbery border, pittosporum can be maintained at any desired height by selective hand pruning. The stiff branches with dense foliage can be sheared if this is begun when they are young. Plant on 4- to 5-foot centers for mass planting.

Pittosporum is highly salt-tolerant, growing right up onto the sand dunes along the ocean, and it grows well on a variety of soils in full sun to partial shade. Growth rate is rapid on well-drained, acid soil of average fertility, although pittosporum can tolerate occasional drought. It does not tolerate poorly drained or wet soil since root rot quickly infects and kills the root system. This often occurs along foundations where drainage is poor or rain water accumulates from the roof or gutters. Unfortunately, many pittosporum plants meet their demise in this manner.

Pests and Diseases

Problems include cottony cushion scale and aphids. Micronutrient deficiencies become obvious on soils with a high pH. Leaf spot and root rot diseases can be problems for pittosporum. To prevent root rot diseases, avoid planting in areas where water accumulates.
