Juniperus chinensis 'Torulosa': 'Torulosa' Juniper1

Edward F. Gilman and Dennis G. Watson2

Introduction

Torulosa Juniper grows into a narrow cone shape when young, then opens up as the plant ages. Although the main body of its foliage is as thick as if it had been sheared, delicately twisted, upright branches emerge gracefully all around the plant, in almost a flame-like manner. It may grow to 15 feet tall in 15 years, perhaps leaning to one side in a picturesque manner. Do not expect a row of them to provide a uniform shape since crown form varies.

Use and Management

Torulosa juniper develops into a showcase specimen without pruning and is probably best used for this purpose. Planted on 4- to 6-foot centers, it can develop into a thick screen which could be useful along a driveway, where a narrow, bright green screen is often needed to create privacy.

Growing best in full sun, more open in partial shade, torulosa juniper needs well-drained soil or it will decline from root rot. It tolerates alkaline soil and is quite drought-tolerant but root regeneration is slow after transplanting from a field nursery. It is frequently offered in containers from a nursery.

Torulosa juniper can be propagated by cuttings.

Pests

Mites and bagworms can infest the foliage.

Diseases

Torulosa juniper is susceptible to root rot and bacterial blight.
