Polyscias pinnata Balfour Aralia1

Edward F. Gilman2

Introduction

Balfour aralia is usually seen in its variegated form of glossy, light green leaves with irregular milk-white markings at its margins (Fig. 1). The stiffly upright growth habit, comprised of many stems, works well as a hedge or screen, or as a specimen. It grows nicely in a container for patio or terrace. The plant may thin out at the bottom as it grows older. Prune several of the older stems to the ground to encourage thicker foliage near the base.

Use and Management

Tolerant of salt spray, full sun or deep shade, balfour aralia prefers moist, well-drained soil where it can be protected from frost. It grows well as a house plant if not over-watered. Plant on three- to four-foot centers to form a screen or mass planting. The variegated forms look good as a specimen or as an accent growing in a shrub border.

Propagation is by seeds, cuttings, or air layering.

Mites can be a serious foliage problem and plants also need to be checked for scale.

Pests and Diseases

No diseases are of major concern.
