Thuja orientalis, also known as Oriental Arborvitae, is a versatile, slow-growing conifer that brings year-round structure and lush greenery to New Zealand gardens. With its naturally compact habit and soft, scale-like foliage, thuja orientalis is an enduring favourite for hedges, borders, foundation planting, or as a statement specimen in mixed shrub beds. Its adaptability to a range of soil conditions, paired with resistance to pests and diseases, makes it an excellent low-maintenance option for both beginner gardeners and seasoned landscapers.

Typha orientalis (Raupō)

5

Typha orientalis, commonly known as Raupo, is a vigorous and erect, NZ native grass. It is found throughout New Zealand in shallow, fertile waters such as sheltered lakes and swamps and will grow in water up to one metre deep. Plants will typically grow to 2.5 m tall and 1 m wide, but will quickly colonise larger areas as the roots spread. Typha orientalis is commonly used in wetland and riparian plantings but is also now being included in modern gardens where it is used in borders and mixed plantings.

Features and Growth

Thuja orientalis stands out with its dense, upright form and gently aromatic, evergreen leaves. Foliage emerges bright green and may take on bronze or golden hues in winter, providing seasonal interest. Height typically ranges from 2-5 metres, but growth rate and ultimate size can vary depending on the cultivar and growing conditions. This conifer tolerates full sun to part shade and is remarkably wind-hardy—crucial in exposed New Zealand gardens. It requires little pruning to maintain its tidy shape, and unlike some conifers, won’t easily grow out of control.

Popular Varieties

Many gardeners in New Zealand love the diversity of thuja orientalis cultivars, each offering unique colours and growth habits. Compact options like Thuja orientalis Aurea Nana display golden-yellow new growth and retain a small, rounded form, perfect for low hedges or containers. For bursts of seasonal colour, Thuja orientalis 'Rosedalis' delights with rosy-tipped spring foliage. If you’re seeking something unusual, Thuja orientalis 'Blue Cone' brings eye-catching blue-toned cones and compact branching, adding character to mixed plantings.

While researching this species, you might also come across Thuja occidentalis, a closely related conifer that shares similar uses and eye-pleasing appearance.

Uses in the Garden

Thuja orientalis’s tidy habit and year-round colour make it a top performer for formal hedging, privacy screens, and evergreen backdrops. It responds well to clipping and shaping, so it’s often planted as a classic hedge or topiary. In smaller gardens or where space is limited, dwarf varieties like Thuja orientalis Aurea Nana provide structure without overwhelming their neighbours. Pair these conifers with contrasting textural plants or grasses for a dynamic effect—consider adding moisture-loving species like Typha orientalis (Raupō) near ponds or rain gardens for a naturalistic, layered look.

Planting and Care Tips

Thuja orientalis is happiest in well-drained soil with plenty of organic matter, but it adapts to clay or sandy conditions as long as extremes are avoided. Water young plants regularly, especially over dry summers, to help establish deep roots. Once established, these conifers are notably drought-tolerant and cope well with the challenging New Zealand climate. A layer of mulch will help conserve soil moisture and keep the roots cool. Feed with a balanced, slow-release fertiliser in spring to promote healthy new growth and enhance foliage colour.

Whether you need a classic formal hedge or a statement specimen, thuja orientalis’s reliability, resilience, and beauty ensure it remains a cornerstone of low-maintenance gardening in New Zealand. Explore the rich variety of cultivars to find the perfect fit for your outdoor space.
